...someone must be able either to confirm or deny - SDI bonus using regs?
This was suppose to have been put in the last PvP publish. Either Pub 42 or 43. It was implemented on test center. It is not in the the Publish release notes.
Now stating this. This does not mean it is not currently implemented. The fact is there are many changes and additions often omitted , overlooked and published.
However what happens is that most players take the Publish release notes on blind faith and adjust their characters accordingly.
Here are a few examples
Now this first one is a bug, but please bear with me.
Publish 18 - UO:R Parry - You will now be able to block blows with weapons at 50% of your parry skill.
Now nobody really noticed this till the time SE was released. At the time if you were a samurai, you couldn't block or evade. This issue was fixed right before ML.
The 80 dex requirement for parry posted in Publish 25. Between SE and ML this requirement was silently taken out to balance out the mess with the machine gun archers, however MRTact I believe re enabled it sometime after ML.
So with that, the only sure way is to test it.
As posted by others in this thread of Duelist using Regs and using a suit to max out properties, the logic isn't there.
As a duelist most would have 100-120 med, 100-150 Int, a hat of the Magi, and a few MR in their suit. SDI isn't much of the issue. It is easily maxed out for PvP. When you duel you are using low end spells to disrupt and damage. So there might be something to this if people are using regs in duels.
