How to understand these constants?

[coconut]

Simple question, im right? if you can explain (?????)
1. +2%
2. +0,3 armor (like 1/3 of armor)
3. +0,5 HP/sec (?????)
4. +25 HP
5. +15 mana
6. +0,5% mana regen (?????)

Correct except for HP and mana, it's a flat value restored per second in normal game speed

1. +2% faster attack speed. This faster attack speed counts towards the -80% to +400% cap to faster attack speed. As such a unit with 200 agility and no debuffs to faster attack speed will cap out on attack speed at 2% faster attack speed per agility.

2. 0.3 armor per point of agility. This fractional armor does factor into damage reduction calculations, even if the UI rounds armor to whole numbers.

3. +0.05 hp/sec
6. +0.05 mana/sec
