Riddle me this…if you have Chrysantherax on a team with troops that give dragons and elementals a 50% mana start…why does Chrysantherax not start the battle with 100% mana. I don’t understand why they don’t stack.
Mana start bonuses specifically do NOT stack. There’s numerous places in the game to get starting mana boosts, and I think some of they say that, but generally they just expect you to know, sadly.
You just get the biggest boost. I guess it does say start with 50%, on each, not start with “an extra 50%”. So one lifts it to 50% and the other lifts it to the same 50%, not higher.
It’s a shame, but I guess they fear higher amounts would be too broken.
Thank God that 50% mana starts do not work like this. 
Palace defenses and other setups could make Guild War defenses a complete nightmare.

You would be completely annihilated and there would be literally nothing that you could do about it. It would make farming even more brain dead than it already is now though.
