Make Mob Debuffs More Effective

...because I can't wait to have excessively difficult boss fights.

But no, really, the current debuffs mobs can inflict are generally imperceptible or merely an annoyance. Currently, they are in almost no way a threat. While weakness and reduction in movement speed is on paper a good idea, in practice, the former has little impact on your damage output and the latter is more irritating than dangerous. Because of this, the debuff-removing aspects of Spin Attack and Heal are much more useless than what it could possibly be.

The solution? Make these debuffs affect your skill points negatively. This would, of course, scale with the level of the debuff. However, this debuff should not affect your ability to use any items; this would be more of a reverse-stat potion. For the currently available debuffs, this would be Weakness for Strength and Dexterity and Slowness for Defense and Agility.

However, there are some issues present in the above. For example, why would slowness affect your Defense? Where does Intelligence come into play here? Because of this, I propose that a) there are five total debuff spells and b) a mob can inflict multiple debuffs (decided by the CT and not randomly selected, of course) with one spell. In general, this change to debuffs would make the possibility of a mob debuffing you just that much more dangerous, and the debuff-negating abilities of mage and assassin to be more useful. Here's an example list of debuffs:

Weakness - Reduces Strength
Mining Fatigue - Reduces Dexterity
Hunger - Reduces Intelligence
Haste - Reduces Defense
Slowness - Reduces Agility

Of course, this list could have problematic effects, but once again, it is only an example list. The general concept is that debuffs become more dangerous because they affect your Skill Points.

What about Warrior, or Archer, you may ask? Well, they won't be able to clear their debuffs, but they can counter them with skills they already have:
- War Scream counters -Def and -Str
- Escape counters -Agi

Pros:
- Debuffs are actually significant in battle
- Mage's cleanse and Assassin's disease are slightly more relatively useful
Cons:
- Bosses become more difficult
- Harder to implement

tl;dr Debuffs act as negative stat pots instead of being vanilla minecraft debuffs
