Getting him to fast-roll territory takes you over the SL99 mark AND U DO NOT WANT TO GO OVER THAT TRUST ME. So just get enough endurance for the 192 stamina, mid-roll and DEAL WITH IT.
You need full strength to one-hand the Golem Axe so you can do its awesome wind attacks to knock people off ledges, which you can't do if you can only two-hand it. WORTH IT BELIEVE ME.
