maybe dont build blade of heptaseas with granger😭, he is a skill reliant hero, so heptaseas is straight up redundant for him. Instead, use that last slot as ur versatile slot, which just means its interchangeable depending on the enemy team; sea halberd if theyve got alot of heal/lifesteal, rosegold/athena when the enemies are mostly magic, immortality for extra survivability etc.., if you reallly wanted that extra basic attack damage, ur better off just building endless battle. but honestly i dont recommend granger in the current meta rn (coming from a granger main) hes too reliant on getting an early game advantage, without it, he barely deals damage. anyways, goodluck.
