Cardboardbox

Special Ability
Cardboard Box has no special abilities until it evolves. Once evolved, it gains the ability to alter any event rewards with the exception of Treasure (Pet Stones or a Lucky Draw) and the Lava-Filled Corridor (extra rooms). It will, on a 50/50 chance, be either Good or Bad to either grant a bonus to the event reward, or steal part of it away.

The bonus starts at 110% of the event reward and the malus starts at 50% of the event reward. These can both be increased by gaining Class Levels, to a total of 145% and 85% respectively, the bonus reaching said maximum at CL50.

This will stack with Clam for any GP, but Cardboard Box also applies to Experience, Pet Stones, Growth, etc. Just not Treasure or the extra rooms granted by Lava-Filled Corridor.

(Good) Increases the rewards from events to (1.1 + 0.007 CL) (Capped at CL 50)

(Bad) Reduces all rewards from events to (0.5 + 0.007 CL) (Capped at CL 50).

The rewards from the Good form eventually outweigh the losses from the Bad form starting at CL 30, with an average bonus of 115% at CL 50.
