I decided to re-roll my Bandit, but this time incorporating base-int with intent to reach the goal of 12,500 HP by 135. I have calculated that if I have 12,500 HP at 135 + 1,452 (Natural HP Gain from 135-200 for Shadower) + 200 (Medal) + 300 (Black Belt) +500 (Hp Quest) + 150 (2 Carat Lovebirds Wedding Ring) = 15,102 HP at lvl 200 or 30,204 effective HP with Meso Guard This is how I am attempting to calculate (Please comment if you notice error) Goal: 12,500 HP at lvl 135 Shadower would have 4,963 Base HP at 135 given NO WASHING.... 12,500-4,963= 7,537 HP needed 7,537 HP/ 22HP (Average gain with fresh AP) = 342.6 So I need 343 Washes wish fresh AP (70 LVLS of fresh AP) by lvl 135 to reach 12,500 HP 343 (washes required) * 12 (MP needed per wash) = 4,116 MP Required MIN MP for 135 Shadower is 2,024, MIN MP cannot be used to wash... So I need 2,024 + 4,116 MP = 6,140 MP by lvl 135 So I need 6,140 MP by lvl 135 to do 343 washes to reach 12,500 Base Hp at target lvl. I also have +110 INT gear / MW20 that will help me accumulate base MP as I go, but to my understand this will not effect MP washing I have read all the literature pertaining to HP, MP, and Double Washing but I struggle to understand 1. Do I need to double wash (HP + MP Wash) to reach my needed 6,140 MP by 135 2. Is 240 base int appropriate ? (I chose this because 240 base= 24 mp gain from MP wash which is enough for 2 washes, it just seems reasonable) 3. Do you know any mathematical technique to calculate ideal Base Int? I ran my current stats through @Shiyui 's Calculator and played with values a bit in attempts to answer my own questions. Here are the results First run I included MP Washing and program recommended Second run I excluded MP washing it actually lowers my cost a bit
