A nice extension to this module would be the introduction of a Mana system. Like many other games, mana will be the main resource pool for (eventually) casting spells. For simplicity's sake, we can assume that mana is equal to the wisdom stat * 10.

For something like this, I would expect to see a ManaComponent, ManaClientSystem, ManaAuthoritySystem, and several mana-based equivalents to the health system events. Specifically these events:

• DoHealEvent
• BeforeHealEvent
• OnHealedEvent
• FullHealthEvent

Optionally, a ManaHUD may be added as well.

While reviewing #2 I skipped multiplayer testing for expediency, thinking we could try it out in multiplayer sometime later at an event or so. One thing I noted was that attack events are handled in one spot, with drain damage adding in or even replacing standard damage.

@StripedMonkey might have already tested it and I may just be misunderstanding the code, in which case we can close this. But I wanted to make sure we had a reminder to check on it at some point :-)
