Checking if unit has a buff/debuff

[MooNek]

Hi, I want to make skill/spell that will deal damage equal to number of buffs(or debuffs in this situation) for example 20 damage more for each debuff on target unit.
Is there anyway to:
1. check how many buffs target unit has
2. Make spell check only for some buffs/debuffs (for example bonus damage triggers only when unit is stunned, slowed or dazed - still +20 per each while ignoring the other buffs/debuffs)
3. Make spell do diffrent effects based on what buffs/debuffs target has applied on.

edit:
I'm using only triggers, never used JASS, but if JASS will be the only way I'll try it.

Just add a code to check if unit has specific buff in boolean, returning true means setting temp point and creating dummy units that will have added a specific ability and it to be casted over the target.

Oh god... checked triggers before posting this and didn't see "Unit has specific buff"...
I'm blind sorry for spamming.

Thanks for the Reply anyway, it made me check it one more time xd
