"In the D&D BASIC rules, a blinded creature may not attack."
A LOAD OF ENCUMBRANCE RULES
Goblin Punch using Triple X Depletion rules. Anti-Hammerspacerules from Matt Rundle has good appeal due to simplicity as does using STR/CON as the number of "slots". Currently, I use LotFP's 5 slots equals 1 encumbrance point method.
