Full STR WAR is nothing to write off.

[OmegaSinX]

Your maths is a bit out... I get 424 STR in full i90 armour and Gryphonskin, with party buff. No STR buff from food unfortunately. You could potentially get an extra 4 (or minus 2) from your race choice.

To be exact, It added up to 446. I will run the numbers again to be sure. I'm Highlander Hume, which have highest based STR in game.
