Obelisk
Creates an Obelisk at target location
Obelisk is similar to pillar in mechanics, it can reflect boomerangs, act as a damage soaker
Obelisk knocks everyone away who come too close to it (including caster, excluding his allies) but it won't deal damage
Lasts 4 seconds, then explodes not dealing damage, but knocking back even further, explosion has bigger aoe
Has about half of hp of pillar
Takes damage if created on lava
Link can be applied to it
CD for spell is a bit longer than other Y spells
With each level of spell - increase hp/decrease CD of spell
