Regen Spells & Light Arts

[Slycer]

So Light Arts definitely provides a bonus to both Regen potency as well as duration, I went and did some testing to see exactly how the bonus works. Turns out it's level dependent for both potency and duration. I updated Regen Spell category page and Light Arts page on BG Wiki with this testing for Regen spells. Here's the raw data, all with Light Arts (done on test server to manually modify level):

SCH Lv. 18: Regen - No duration bonus
SCH Lv. 35: Regen - +12 seconds, +6/tick
SCH Lv. 40: Regen II - +18 seconds, +9/tick
SCH Lv. 50: Regen II - +24 seconds
SCH Lv. 80: Regen II - +40 seconds, +19/tick
SCH Lv. 99: Regen - +48 seconds, +24/tick, Regen II - +48 seconds, +24/tick

Previously known:
The potency bonus is flat across all tiers of regen (tested with all Regen spells).

New stuff:
First, I think the duration bonus is a constant # of seconds, not a percentage, as Regen (I) has a greater base duration but seems to get the same duration bonus (in seconds). Second, the duration bonus is not # of ticks because the spell will end between ticks at certain levels. Third, I couldn't test potency because I had no easy way of dropping my HP at levels below 35 on the test server (was using sublimation to drop it), but there's definitely no bonus for at least duration at some level X and below. Level 18 gets no duration bonus for sure (Regen was exactly 75 seconds). If I had to guess, I'd say piecewise linear going from 0-18 seconds from 25 and 40 and then 18 to 48 between 40 and 99.

My theoretical equations for the bonus are (level-1)/4 rounded down for potency (I would have said level/4, but level 80 at 19/tick, for example, wouldn't fit). Double that number, in seconds, for duration seems to fit reasonably well. This doesn't fit the duration data perfectly, but it's close for a first pass.

There are some blanks I need to fill in to verify this info, but does this seem correct? Any other input?

Specifically interested in the following:

-How does the equation change below level 40 (and is it level 40 where the equation changes)?
-What's the minimum level that receives the bonus (and is that minimum different for duration and potency)?
-More info for duration bonus?

Potency bonus:
35 and below: 3.5*(level/18), Duration bonus = Potency Bonus * 1.75
40 and above: 9*(level/37), Duration bonus = Potency Bonus * 2

3.5*(35/18) = 6.8

3.5*(40/18) = 7.7, actual was +9
So the breakpoint is less than 40.

Now to narrow down the breakpoint, go find the +Potency at 37 through 39:
3.5*(37/18) = 7.1
or
9*(37/37) = 9

3.5*(38/18) = 7.3
or
9*(38/37) = 9.2

3.5*(39/18) = 7.5
or
9*(39/37) = 9.4

Include the decimal, and duration bonus is just the potency bonus x2 above the breakpoint, and perhaps x1.75 below. So I've removed the flooring step above and it'll just be presumed on the potency.

9*(40/37) = 9.7, *2 = +19.4sec
9*(50/37) = 12.1, +24.2sec
9*(80/37) = 19.4, +39.8sec
9*(99/37) = 24.0, +48sec

Also, I haven't done any Tabula Rasa testing yet, so I need to do that. I assume that Tabula Rasa is 50% bonus across the board (duration and potency), and also dependent on level, but the only data I have for TR is that it adds 36/tick Regen at level 99 (did not check duration bonus or effect at other levels).

Another thing, since the Regen bonus was increased from test server to final implementation, I'd have reason to believe that the Helix/Dark Arts bonus might have received a similar increase, but this has not been tested yet as far as I'm aware. Has anyone looked into Helix damage bonus since implementation? I assume it gets a duration bonus as well? This would be fairly easy to do and I can check myself, I just want to see if anyone else has done it first.

As far as the Light Arts/Regen stuff goes, if I get bored I'll probably just spend some time and do it level by level for 15 levels or so from 30 to 45 and see how duration/potency go up, and then again for something like 75 to 85.

Also, if anyone can test, are we sure that Orison Mitts +1 add 10 seconds duration? Seems weird that they would make a piece of equipment increase the regen duration by some amount that makes it end between ticks.

It's not unprecedented, in that Meditate enhancing gear has been adding 4 seconds for ages, but it would be weird I agree.

200/1024*Level Below and 250/1024*Level Above the breakpoint works too.
