My current HP is 100K. This is full buffed, no remedies, no elate and full STR build, this also includes the HP buff that fury get from bless and I'm missing 5x Life7 because I chose not to link it.
Rec Remedy = 15 REC = 375 HP
Christmas R = 700 REC = 3500 HP
HP Remedy = 500 HP
Health Remedy Lv2 = 1700 HP
Health Remedy Lv3 = 3500 HP
Elate = 650 REC = 3250 HP
5x Life 7 = 10,000 HP
Costume = 10,000 HP
Vitality REC Training = 900REC = 4500HP
Lv80 HP Guard Skill (forgot name cause I can't login) = 2000 HP
(thanks Hezam for reminding me of Vitality REC & 80 Skill)
All of these total add: 39,325 HP
Lets say I went full REC and had 4000 REC total (2000 more than I already have)
2000 REC = 10,000 HP
Total of 149,325 HP. Which means 145K might be possible, but I'm just estimating on the extra REC if I was full REC, you might not even be able to pull off 4K. I'm also not sure how the extra HP from bless works (per level or %HP) if it works off %HP then it's possible you could get 145K, but only on a fury Guardian.
For a Light, since they don't get the extra HP from bless, I'd say he was probably lying. If calculations are right (1REC = 5HP) then this should most likely be the answer to your question.
