I recently aquired a 'Tome of Greater Strength III' which, apparently adds +3 strength to any other item.I think (although I am not 100 % certain) that this is applied in the same manner as an elemental resistance or enhancement.When I use this I believe it will (radically) alter the 'level required to use' of the item it is applied to .How can I know what the new required level would be ?I really don't want to create a beautiful new item that is beyond my means of using because the level has been bumped way up.So, I'm wondering if there is a formula someone can point me to ?Or could a GM help me out by doing some 'off line' dry run simulation/creations ? Any other thoughts/ideas would be appreciated.Thanks
