to remove hide of an enemy:
1. use any aoe (area of effect) skill in his proximity (guess where he could be and use it)
2. in olympiad there is a talisman (Battleground talisman) that removes hide in a wide area and the possibility to use hide
3. there are 2 types of evasion: normal attack evasion (stat shown as 0-300 in character stat pannel) and SKILL evasion (not shown in stat). Skill evasion is given with a chance for othel class for a short duration, after which skills can be used to hit othel.
NOTE: there are skills that completly ignore evasion also (specified in skill description)
There are classes with more then 1 hyde skills (sayha), which is why the above are crucial to have knowledge of.
