This is a suggestion to fix various problems with fireball and other spells.
Current fireball, lock on an enemy...throw spell, hope it gets there due to many invisible obsticles that
we can't see and may cause it to prematurely detonate.
I hate it
Better way...
You click to throw a fireball, your curser now moves a ground target point where ever it is pointing, if that is a clear
target "enemy" it is green, if it is blocked...it is red. Also if your not pointing at a particular enemy, the target
is on the dungeon floor...also red if blocked, green if clear.
When you have a 'green' shot...either an enemy or the groud, click again to fire.
This would work great with..ball spells, walls or any other spell that SHOULD be ground targetable.
