Game Mechanics: Stats/Resists apparently not capped serverside

[Technique]

It's possible to buff them above 255 or debuff them below 1, despite what the client displays.

At a glance this doesn't alter derived attributes such as HP or mana, but it does affect debuffs, as amounts are being subtracted from the actual stat value rather than the capped value, and I'd imagine it also affects any other calculation that doesn't impose a cap on stat inputs.
