Cap?

Is there a cap on the effect? Wearing the Arch Mage Robes (100%) and Morokei (100%) doesn't seem to regenerate any faster than the robes alone Fowl 22:52, 7 December 2011 (UTC)

I'm not sure with the cap of the regenerate magicka but it would seem that fortify magicka regenerations has nothing to do with how fast you regenerate your magicka during battle. The regenerations speed kicks in outside battle. From what I have read so far in battle you regenerate one 1% of your magicka per second(not confirmed yet). Not sure how bethesda did the mechanics, but if true it may make regenerate magicka one of the most useless enchantments you can have in battle. Not sure if it was intended, an oversight or a bug. — Unsigned comment by 113.10.83.65 (talk) at 16:26 on 16 December 2011

I remember Morokei and the Arch-Mages robes helping in combat in the 1.1 patch. Perhaps Beth broke magicka regen in 1.2? Narzul 04:55, 17 December 2011 (UTC)

Fortify magicka regen definitely still helps in battle - my Mage combat regen definitely changes as I add and remove +regen (morokei, robes, rings etc) - but for the numbers I have had to follow what I have read. The base regen rate (from what I have read) is the 3%/s out of combat, therefore 1% in combat. Fortify magicka regen applies to both. So +100% magicka regen from gear would give 2% regen in battle, 6% out of battle. 78.119.214.247 11:55, 20 December 2011 (UTC)

Does this still apply? There are no additional Actor Values to determine in Combat Magicka regeneration as far as I can tell. Is in combat magicka regeneration not the same as out of combat regeneration now?Unclejack (talk) 00:11, 4 July 2013 (GMT)

In my tests Magicka Regenaration does not appear to be capped, and does work properly past 100%. Having a 250% Magicka Regeneration will recharge magicka faster than, say, a 120% Magicka Regeneration rate. --Rope Dog (talk) 04:43, 10 July 2013 (GMT)

"Fortify Magicka" vs "Fortify Regen Magicka"

I just wanted to point out that while at low Magicka levels, "Fortify Magicka" is more efficient, at high Magicka levels, "Fortify Regen Magicka" is more effective:

If you go the "Fortify Magicka" route (using the above numbers), you can cast 2.666 spells before waiting 33.333 seconds, while the "Fortify Regen Magicka", 2 spells and 11 seconds. Comparing larger (whole) numbers, this effectively becomes (with recharge time at the end):

• "Fortify Regen Magicka": 8x + 44.4s
• "Fortify Magicka": 8x + 100s

Cumulative Effects?

This has been marked as a question that needs to be answered.

how do the regeneration effects add together? im asking specifically about the atronach stone, which is -50% regen. so if im wearing the archmage robes/morokai/aetherial crown with apprentice stone etc., how does it effect? does it go back to 100% (50% of (base(100%) + 100%)= 100%) or is it still higher (base(100%) + 100% - 50% = 150%). Likewise when adding positive effects, (morokai & archmage) does it add by (base(100%) + 100% + 100% = 300%) or multiply by (100% of (base(100%) + 100%) = 400%)? How do effects add? — Unsigned comment by 124.148.89.183 (talk) at 13:41 on 12 November 2013 (GMT)

Basically, bonuses/penalties are summed first. Long version: the player's absolute magicka gained per second is something like (maximum magicka)*(MagickaRate/100)*(MagickaRateMult/100), where MagickaRate is initially 3 and MagickaRateMult is initially 100. Being in a state of combat (i.e. being near hostiles) further multiplies that by 0.33. Effects that say they modify magicka regeneration do so only by adding or subtracting their magnitude from either MagickaRate or MagickaRateMult, although hardly anything modifies the MagickaRate of the player (I only know of the Highborn power, Ring of the Erudite, having the Staff of Jyrik Gauldurson equipped, and being in Vampire Lord form). -- Lid-Mop (talk) 23:16, 2 August 2014 (GMT)
