Talk:Magic penetration/@comment-142.197.196.173-20121005041154

I just ran some numbers... well, actually a lot of numbers. I was using excel. Anyway. I did a bunch of mathy stuff and found that magic penetration is rather underwhelming. Not bad, mind you, but not some top-secret own-sauce stat.

Very early game, MP is worth about 0.9AP. In other words, each point of MP is worth less than each point of AP. However, after buying basically your first AP item, this equals out and by end game, each point of MP is worth roughly 1.1AP.

In other words, when considering the value of an item, you can basically just consider MP as AP to simplify your decisions. Planing for end-game, add 10%.

This also makes Void Staff one of the most gold-efficient items in the game as far as pure (caster) damage goes.
