Written by AllCooperAgain. Thanks for taking the time! (I edited capitalization, skill names, and fixed a few things)
Most people won't care to read this, but it can be useful for specific questions. 99% of this page is obvious. I'll have a history of updates if we change anything major. Please know that this game is perfectly playable with just basic intuition, common sense, and good intentions to race not kill.
Please see the original thread here on the current version of rules we are playing by:

Try not to take offensive runes. The only runes you should need are defense and utility (armor, magic resist, health energy and mana and their respective regens, CDR, movement.) Penetration runes, attack speed, damage, and ability power runes are not necessary and hurt gameplay.
