Boom Beach: Powerstone Receive Chance on Attack

I did some research because I wanted to know if I should keep my Dark Statues that increased my Powerstone acquisition chances.

tl;dr - Dark Statues aren't really worthwhile until later in the game.  idols and guardians just don't have enough benefit to warrent the space they use.


Without statues, you have a base change of 25% to receive a powerstone when you destroy the Headquarters and a 2% chance on all other buildings.

Except for when you raid a blackguard HQ, here is the percentage breakdown for receiving power stones:

85% chance to receive a Fragment
12% chance to receive a Shard
3% chance to receive a Crystal

Here is the kicker!  Dark Statues apply a multiplicative increase in drop chance, not an additive.

This means if you had +100% drop chance from Dark Statues, you would only have the following:

50% chance the headquarters will drop a power stone
4% chance on all other buildings.

O_o

I think I will stick to the other three types of towers for now.
