Spear is fucking awesome once you learn to ignore the charge up special, the first spear is the best in my opinion.
Sword sucks, I am bad with the sword so the sword sucks.
Shield is fun, I like the shield. All 4 shield are good but Chaos' is the weakest in my opinion.
Bow is okay, it's all about how you use the special. The fourth bow is awesome.
Fists are fun, I am not that good with them but better than with the sword. The fourth fist is funnerer.
The gun... The second gun, I think it's the second the one where getting hit with your explosion buffs your attack for a few seconds, is good. If you get the hammer upgrade that lets you fire three mortars it's fantastic, get Cluster Bomb and it is border line easy mode. Even on Heat 32 that Triple Shot or Cluster Bomb is game changing. Add Delta Chamber to the mix and now we are cooking with gas!
One of the "tricks" every one probably knows is to stack your damage. Take the mirror buff where when you have two negative status thingies on a mob it takes extra damage. Then work your boons so you are constantly doing that bonus damage. Rupture, Jolted, Doom, Hangover, Weak, Exposed, and Chill all count. Overlap that shit, plant a blood shard, and Ka-Pow!
My fav combo is the Hermes +run speed, +run speed on dash, deal bonus damage based on run speed bones, Zeus' bonus to damage after using a call, the above shit, and Artemis' call. You do
half of Hades' health bar in one call if you time it right and get high level boons.
This is an excellent game.
