Attack calculation

[Prof Evbof]

I am playing a level 15 scrapper - Martial Arts and Dark Armor. I have a few attacks from Power Pools as well.

The combat log shows my chance to hit. For my three power pool attacks, the value is exactly as I would suspect if the base to hit is 75% and the beginners luck for my lvl 15 is 3%.

However my martial arts attacks have a higher chance to hit.

I have Hover, Dark Embrace, and Murky Cloud as toggles and I don't expect any of those to give buff to hit - and especially not to just my martial arts powers.

What other mechanic am I not aware of?

Martial art powers get a slight bonus to their accuracy.  The base is 1.05 instead of 1.00 meaning 78.75% instead of 75%
