Can the demonslayer get a buff on it or at least a way to show it did proc?

You *should* be able to hit a 39 when it goes off, but theres no way to actually tell if it did.

I tested it before using all the +power items we can get, which if i recall, gives 93 or 95 power (cant recall off the top of my head which it was)

Either way as you can see, 37 is the max

However, demonslayer should add +9 to that, so either 102 or 104, which either would hit
39.244882499999996
or
39.72489

During my tests the most I ever saw it hit on a black demon was a 37, and had multiple hits there, so either it wasnt procing, or would happen to hit a 35 say, and the +9 move that to a 37.

Also tested it with no pot, no prayer, just aggressive, which should allow for a 29 hit (with the demon slayer vs a 27 or 29 (depending on the 93/95 max power).  Never saw one of those hits either.

TLDR
Can the demonslayer get switched to +9 100% vs the 50 so its more worth it to use when farming them?
or
When it procs can the damage marker change colors to like a red background with black text (currently its red and white) (like the poison is now green) so we at least know it DID go off.
Or
Both...100% so its more worth it, + the damage color change when fighting demons.
