Advanced Penetrating Boost Potion
Advanced Penetrating Boost Potion is a potion (consumable) in GMS v271. Sells to NPCs for 1 mesos.
Only Alchemy Masters can make this potion, which increases your Ignore DEF by 20% for 40 minutes.
Normally, only 1 potion can be used at a time, but Alchemists can use 2 if they are of different types.
However, even Alchemists cannot use 2 of the same potions at once, and Boss Rush Boost Potions, Great Hero Boost Potions, and Great Blessing Potions cannot be used together.
