Weapon size modifier table

The same weapon does not deal the same damage to every monster. Each weapon type has its own effectiveness against Small, Medium and Large targets. This is the game’s own Weapon Effectiveness table, laid out so a number can be found in seconds.

How to read it

A cell is how much of your weapon lands on that size. 100% is the whole weapon; the lower the number, the less it delivers against that target. It applies to magic damage too.

No penalty anywhere, only Bare-Handed, Wand, Staff and Foxtail Grass. Everything else has at least one size it is bad against.

What removes the penalty

Card: Drake removes the weapon effectiveness penalty. If your weapon has no penalty, it does nothing at all.

Illusion Card: Drake is not the same thing. It has a 5% chance on attack, lasting 1 second, with a 1-second cooldown — it does not remove the penalty, it interrupts it now and then.

Outside of cards, the Blacksmith’s Weapon Perfection removes it too.
