However, from what I've seen, dragon claws ALWAYS hit. I haven't seen a 0 0 0 0 spec yet. The worst I've seen is 0 0 7 8 so far. Even on someone who was in torags and praying melee it was hitting.
Dragon claws have many aspects you are not taking into account. It hits 4 times in 1 spec, and those hits are based on the first number you hit. Dragon dagger is 2 separate hits in one, neither based on the other. If you hit a 32 on one hit, the other might be a 0. Dragon claws actually look a LOT more accurate with the spec -- again, I've seen them doing a lot better than DDS against people with 99 defence.
Also, I know you can't get 1 hit at max HP, but you can get 2 hit at max hp. My friend got 2 hit like 5 times in a row by dclaws in good gear.
DClaws may not say they're more accurate, but from the looks they always hit. So its pretty much gauranteed that DClaws is more accurate. It's a little hard to explain though, with the way dclaws seem to work.
When you 2-hit someone with DSS, maxed stats, brewed, and using tuna potato + brew, post a video please...
I owned d claws briefely for about 1 or 2 days and with 90 attack my worst spec was 0-1, I did not get 4 hits.
