Has some corrections actually....
I believe the wiki's improperly attribute every rank of stealth to be +20%.... ranks 2-5 are only worth 5% each
Also told me that the sword spec in 1/2 hand adds to crit damage as well as crit chance for ranks 2 & 3... they roughly work out to a 5% increase in damage over time per rank.
Also got some figures on the Axe bleed damage... does 1-3 DPS for 4-6 seconds... with the higher ranks ending up on the larger end of those ranges. ( I think it works out to 1dps for 4sec, 2dps for 5, and 3dps for 6 for the 3 ranks)
All in all... I am massively unimpressed by the weapon specializations... other than the War Hammer one which lets you ignore 75% of enemy armor.... that's huge against heavy armor bosses. Sword is totally skippable... and I don't see the Axe one adding all that much damage either (1-3 damage per second isn't much compared to the damage per swing)
The +20% dmg per rank 1st tier perk out strips the Sword and Axe perks by miles. Axe might be worthy if it stacks bleed damage... but I think every hit just resets the timer. Otherwise I could see using dual light axes to stack those (and may as well throw on some enchantments to further increase dmg per swing)
It's a decent resource anyways... and more reliable than the wiki's for sure.
