So last day I did a major yest of strength. When I beat the guardian I got a guardian sword with great attack +20 (so it had 60 damage). The thing is, I checked my inventory and I had another 60 dmg guardian sword, but that one had attack +20 instead of great attack. So what's the point in having attack+ and great attack when they can be the same? Maybe attack+ could be up to 15 extra dmg and great attack for more than 15, or maybe based on percentatge.
