Wretched Gorge 3 (WG3)

[reckoner]

These are my recommendations to run WG3 with a

very high success rate (95%+ success). It is

possible to successfully do WG3 with weaker

teammates or different setups, but if everyone meets

these guidelines, I feel that your success rate will be

quite high.

1. WG hero bases level 17 at a very bare minimum

  (so they have the maximum attack range). Level 25+

  bases are highly recommended. The weaker your

  heroes, the stronger your bases need to be.

2. Strong heroes.

  2a. Evolved or double-evolved heroes. Evo/Devo heroes

      can take advantage of artifacts, and they also have

      a lot more HP and more damage than non-evo

      heroes. Heroes should also be sufficiently high

      level (9-star at a minimum).

  2b. Heroes should have sufficiently high skill levels.

      It depends on the hero, but in general, skill 7

      should be the minimum.

  2c. Heroes should be sufficiently inscribed (80+).

  2d. Heroes should be crested with revive, if you

      want a higher chance of success. Your

      Pumpkin Duke is the most important hero

      on your team, so at least he should have

      revive.

3. Proper base setup. See the diagram below.

4. Use 3 towers at most, with lower numbers of

  towers also acceptable (using no towers is also

  fine, especially if your towers are not leveled

  past 20). Towers should be as close to the bases

  as possible, and be properly garrisoned. I prefer

  canon towers because they help clear the

  early waves faster, and therefore protect your

  heroes. Arrow towers can do significant damage

  to the demons but don't do AOE damage. I don't

  recommend magic towers because the demons

  can't be stunned, magic tower damage is very

  low, and if they stun regular enemies in the just

  the right spots, your heroes may run out too far

  and get picked off.

5. No walls.

6. Proper hero selection and placement, discussed

  below.

Hero selection and placement:

1. You need a healer, and you need a

  Pumpkin Duke. Ghoulem is preferred, but 

  Druid is acceptable. If you have Ghoulem,

  put it in spot #1 and put PD in spot 3. If

  you don't have Ghoulem, put PD in spot 1

  and Druid in spot 2 or 3.

2. Spots 4, 5, and 6 should only be ranged

  heroes. Do not place melee heroes here.

3. Vlad or Santa (or both if you have them).

  If you don't have either of these, you won't

  have a good success rate in WG3. These

  heroes are needed to clear the waves

  quickly, before they can proc. I prefer to

  place Vlad in spot #5.

4. Aries is really useful to keep the demons

  from proccing too often. Having a hero

  with Eye of Garuda is also recommended

  for the same reason.

5. Using Harpy Queen or Moltanica can

  help negate some of the damage from the

  demons (you don't need both, since you

  also need some high DPS heroes).

6. Do not use heroes that can tank the

  demons without dying, especially if they

  are on one of the outer bases (spots 4,

  5, or 6). Do not use Dread Drake or

  Skull Knight. Any heroes with high life

  drain should not be used, unless it's a

  Pumpkin Duke or Ghoulem/Druid.

7. Do not use Cupid or Valentina. These

  heroes have long cooldowns, and are

  really only good on the 1st wave or in

  short battles.

8. The remainder of your heroes should be

  high-DPS heroes, specifically, heroes that

  hit multiple times per second with their proc.

  Recommendations are Phantom King, 

  Immortep, Snowzilla, Dracax, Medusa,

  Lady Leo, and Beast Tamer.

The 4 players who join a WG3 run should

move as close to one edge of the map as

possible. This placement is preferred over

taking the center of the map, so that the

2 weaker players can be "sheltered" at the

edge of the map, and also to reduce the

chances of failure via a stalemate on that

side.

These are just my recommendations. As I

mentioned before, it's possible to succeed

with different or lesser requirements, but

everything I've mentioned above will boost

your odds. There always will be a chance

of failure due to the randomness of the

spawns.

Quick update for newer heroes:
It's not recommended that anyone use
these heroes in WG3:

Dread Drake
Michael
Skull Knight
Anubis
Grimfiend
Rockno

These heroes are difficult to kill,
and can cause a timeout. If you
absolutely need to use one of these
heroes, do not place them on the
outer edges of the combined base.

Likewise, any hero with strong
defensive talents are not
recommended, such as high level
life drain.
