HP Recovered While Healing
From FFXIclopedia, the free Final Fantasy XI encyclopedia
While resting, your character recovers a set number of Hit Points every 10 seconds. Equipment with this trait will increase this set number of HP recovered.
Base recovery rate starts at 10 HP and increases by 1 every tick. With Signet active in a pre-ToAU zone, base recovery rate increases 3 HP per 10 levels over Lv.1, and the amount healed increases by 1 HP per tick for every 300 maximum HP, capping at +5 with 1200 HP.
All increments are cumulative. If you are interrupted while healing (from standing or being damaged) recovery is reset back to base. If you are healing, even at max HP and MP, and your max increases during this time (such as coming out of weakened status), the culmination applies, and you will not start healing at base.
Amount healed = (10+hHP)N + N(N+1)/2 where N is the number of healing tics. A /healing tic is 10 seconds, but the first tic takes 20 seconds, so be sure to factor that when calculating the number of tics over time. (For example, if calculating how many tics there are in 5 minutes, do 5 * 60 / 10 to determine the number of 10 second tics, then just subtract 1 tic to factor-in the first 20 second tic.)
