For clarity, this augment is indeed meant to give +15 Sunder DCs, as stated by its in-game tooltip. Is there somewhere in game that's indicating +17? If so, please let me know so I can track down the misbehaving tooltip.
I was the original person to add the Minor Artifact values to the wiki. When Isle of Dread first came out, I put all the augments in a normal slot and a Minor Artifact slot to see what values would be increased and by how much.
I noticed that the effects log in the chat gives some additional info not listed in the descriptions:
- Equipping a Minor Artifact with a Claw:Trip augment in it, it states "+15 bonus to Trip DCs, +17 bonus to Improved Trip DCs"
- Equipping a Minor Artifact with a Claw:Sunder augment in it, it states "+15 bonus to Sunder DCs, +17 bonus to Improved Sunder DCs"
- Equipping a Minor Artifact with a Claw:Stunning augment in it, it states "+15 bonus to Stunning DCs" (there is no "Improved Stun" ability)
- Equipping a Minor Artifact with a Claw:Assassinate augment in it, it states "+17 bonus to Assassinate DCs"
So the effects log seems to imply that
only Improved Trip and Improved Sunder would get a +17 bonus, and the normal versions would still get +15. To be fair, I didn't actually test if the Improved versions were truly getting the +17 bonus since I was preoccupied with testing other stuff at the time. I just relied on what the effects log was stating.
Unfortunately, it seems that someone has edited what I originally put on the wiki (
https://ddowiki.com/index.php?title=Dinosaur_Bone_crafting&oldid=532517) - they took out the 'Improved' parts and also said that Stunning gets +17, which it doesn't. Such is the nature of wikis.
I can edit it back, though I suppose to be truly thorough this time I'd like to test if Improved Trip and Improved Sunder actually get the +17 bonus or if the effects log is wrong.
