I'm a newbie in programming (although an informatics olympiad student) and how do we make this in GUI? Let me explain. The ice shard is the skill, the projectile moves to about 1600 range, damaging units that are in its path, at the end it created some ice shards to block the enemy (See http://www.youtube.com/watch?v=Q3WZdGNqrfc). Walrus Punch is the skill, we just click or press the hotkey. Then a buff on ourself appears. We have to attack an enemy within 10 seconds. The attack deals 2/3/4x critical if the target is above 50% HP, if 50% or lower it will deal more (let's say 3/4.5/6) and the target is impaled to the air, but no stun. Instead of it, there is slow for 4 seconds after landing. The video link is same as above. Also, how to change the map size? Thanks a lot... =)..
