WHM lilies should generate on cast to teach about ABC

[Haadrak]

How about instead of just giving lilies from casting spells, casting burst damage or heal spells successfully reduces the timer to get lilies by x-seconds? Maybe like 2 or 3 seconds?

I really like this idea. This way even if you're in a situation where you can't hit things for whatever reason, you're still getting lillies back but the better you play the faster you get them back.
