There is conflicting methodology between how weapon sizes are increased in the Pathfinder Roleplaying Game Core Rulebook in the Equipment chapter and in the appendix of the Pathfinder Bestiary. Additionally, the equipment table is woefully incomplete. Please use that table only for one-step size changes for small to medium or medium to large. All other increases, please do your first size increase on the equipment table and use the table on this page for the remainder of the increases. For example, if you have a Glaive dealing 1d10 damage, a large Glaive (according to the table in the Equipment chapter of the Pathfinder Role-Playing Game Core Rulebook), should deal 2d8 damage. A huge Glaive, according to the table below, would deal 4d6 damage (one step above 2d8).
