Besides breserker what are the best hero aids for colosseum and the arena
Crushing power. Ultimate one shot destruction. Either that, or 1 hero which can shoot up everyone at once incredibly fast. Hero aids meant for these 2 purposes respectively are Skull Mage, Saph or Hydrassaur for the first one. A Tyrants Brand is a must if you want to have a chance against enemy Berserker aids. The second one involves getting a Thunder Blade and Blockhead aid. It's all about you pushing the buttons first before somebody else does.
I am using ent bez pg aids in coli.
For arena, you don’t necesscary need to kill all enemies to win.
I use goli divine 3, wonton divine 3, renee divine 3, then wonton divine 3. Normally I won by destroying the building without kill any enemies! Otherwise ambrosia divine 4 or 5 with ironclad aid should destroy the building as well.
