hope this helps, welcome to a small guide i'm writing based off my own mishaps that will help you.
This game is based of Warcraft 3's mod DoTA, if you've played LoL you'll
know it's pretty much like that game style, if you've played HoN then
you'll know that DoTA 2 is almost exactly like HoN, anyway on to the
basics!
1. This game is entirely skill based for kills, auto attacking almost
gets you nowhere there are only a few characters that NEED auto attacks,
otherwise, utilize your skills! *auto attacking minions isn't a good
idea, regardless of who you are, LAST HITTING IS THE BEST WAY TO GET
GOLD WITHOUT PUSHING YOUR LANE.
2. mana is depleted INSANELY fast, so i recommend starting with 1-2 mana
pots or using your abilities sparingly until you've got mana
regeneration.
3. You're pretty damn squishy, yes i'm aware there is such a thing as
"tanks" however, in DoTA 2, they don't exist. simply put, TRY not to get
hit with a skill as much as possible, use heals if needed or an ability
that blocks damage, if you get ganked, most of the time you'll die.
4. The best way to start out (and this is how i learned) is getting 3
iron branches, a tango, a mana pot, rest of the gold is decided based on
your char, for example, intelligence should get a +3 int item located
under attributes, strength a +3 str item, and agility +3 agi item. now, i
usually get 3 iron branches, but some builds don't necesarily need it
right away, normally there is a built-in recommended build, usually the
starting items section works out well, i have not failed using it with
many champs so far.
5. Wards ARE NEEDED! even if you're not support GET ONE, if bottom or
top, put on in the river, MIA's are a MUST, ganks happen quite a bit and
can happen at any time, CC's in this game last a long time, and hurt.
Observer wards don't reveal invisible units and cost less, Sentry wards
reveal enemy units but cost more, only get Sentry wards if there is an
enemy that can go invisible for long periods of time like "Riki".
6. it's recommended to start with range heroes first to get used to it
because you can keep a distance from minions and last hit them from a
ranged area, it works that way. ranged heroes normally win lanes early
game, you better hope you have at least a ranged ability or ranged hero
with you in lane to farm creeps.
7. THIS GAME IS ENTIRELY TEAM BASED, 1v1's don't normally happen, if
they do, you better hope you have better abilities due to the fact that
your abilities don't scale with AP or AD or attributes.
8. FARMING IS NEEDED, farming is what wins the game, sorry i meant gold,
gold is what wins the game, farming is the means, yes hero kills help,
but they're not top priority, TOWERS are the main objective, if you
have a choice of a tower, or a kill, take the tower, no matter what.
farming is but a means to getting gold as well towers give gold.
9. if you die, you lose gold, it's not like HoN or LoL if you die, you lose gold, DON'T DIE.
10. Feeding is extremely deadly in this game, if a champ is fed, they
snowball like mad and are normally unstoppable, 1 kill/assist gives you 1
level normally out of 25 levels, not once have i killed someone and not
gained a level (either coincidence or true)
11. yes you can buy-back, but don't do it unless absolutely necessary or
fed! it's pointless especially early game! waste of gold...
12. Towers attack fast, they may not do much damage, but don't get hit by them! the damage will rack up!
13. Don't let minions hits you! get the minions to attack each other! they hurt otherwise
14. play co-op matches until you get used to the game, the community is
nice in the fact that they know it's just a bot match. *bot matches
don't count for anything*, you can also make your own game and have just
bots, no human players except you, doesn't help except with learning a
character.
15. to Deny creeps (meaning killing your own, to prevent enemies from
gaining exp/gold) press "A" then click on the creep to auto-attack it,
try to last-hit it, otherwise you're just weakening your forces, also
abilities won't work on your own minions, UNLESS ability specifies it,
just like Doom Bringers "Q" ability.
16. Pulling: Pulling, which can be done in Top Lane (for Scourge) or
Bottom Lane (for Sentinel), is where a hero attacks a jungle-creep spawn
and lures them up/down to where your teams' attack forces (AKA
'players' Red and Green) march by and have them chase the jungle-creeps
back to their spawnpoint. While somewhat effective, it can also be taken
advantage of if done late game due to exposing your teams' towers to
the other team, allowing either for them to destroy the tower or
critically damage it.
17. Push-Back: Similar to Pulling, however instead of requiring the use
of neutral creeps, or Jungle-creeps, or a specific lane (since it can be
done in any of the 3 lanes) it simply requires key movement strikes of
your hero or another players' hero. When your teams' attack forces
spawn, they will eventually (By the time they reach the 2nd of the 3
towers in the lane) line up into a single-file line. By moving your hero
directly in front of their movement line and repeated stop-and-go
movement, you'll slow your attack forces' down to the point where when
they reach the 3rd tower, that tower will be able to help attack the
enemy teams' attack forces, allowing easier XP gain, and somewhat easier
gold gain, as well as the possibility of ganking the enemy heroes.
18. It is highly advised that you read up on what skills do what damage,
and if they are time-based, such as if they're better used during
daytime or nighttime.
19. Some more hero based tips:
If you are playing an initiator (prime examples include tidehunter, sand
king, or earthshaker) be sure to get a blink dagger! It helps so much
to be able to blink into a fight, pop your ulti, and the other team
takes a bunch of AOE damage.
19a. For the gankers out there:
Most gankers have fairly low base health. With the rare exception of
maybe nightstalker or pudge, depending on your build, you can get killed
pretty easily. So a helpful tip would be to always gank with a buddy.
Don't just roam the woods looking for someone on your own, because most
likely, they have more teammates just around the corner.
19b. And for the Carries:
Please try your best to not die. Carries are the prime targets for any
harassers/gankers, especially early game. Just try and stay alive until
mid game, where you become just ridiculously awesome.
19c. Lastly the Supports:
Be sure to play the support role. I know a lot of supports that don't
buy the courier or any wards. It is very important that you do this. It
is perfectly acceptable for a support hero to have little to no kills or
last hits, but as long as you play the support role, you're doing good.
(There are a few exceptions, ie Invoker based on how you play him. But I
guess if you play Invoker, you aren't reading this thread...)
20. One Last Note:
Before you try out a new character, it can help immensely to watch a
game of them playing, either through DOTA or YouTube (I recommend
watching Purge @ purgegamers). Then try them out vs bots. Once you're
ready, then go for the pub game.
