Read through a bunch of guides on this site, sometimes with conflicting answers. I want to hit 30k by 180. I took the natural HP for heroes from Plenty's guide. Estimate of 9700 HP by level 150. Average HP gained on level up by warriors is 66. So natural hero HP at level 180 is 9700 + 66*30 = 11680. The amount of HP I need to additionally wash is 30000 - 11680 = 18320. 18320 divided by the average HP per wash, 52, is 352.3. That's the number of washes I need. The MP consumed per wash by a hero is 4, so 4 multiplied by 352.3 = 1409.23, rounded up to 1410, the amount of mana I need above the base. I estimate to be self-leeching this character for 120 levels, so I divided 1410 by 120 to get 11.75 mana per level, rounded up to 12. So, I should have 120 INT with gear for at least 120 levels. Please let me know if there is a more optimal way to wash to 30k, or if there are any errors in my calculations. Thank you so much!
sounds about right, although i have never washed a Hero, but i have helped my mate out with crunching some numbers, we also ended up with 120 int ish. Nice to see a someone asking for help that at least has tried to calculating it on their own. Kudos to you my man! Most people reset their base int at lvl 135 cuz thats when u can boss btw
Calculations seem right to me, I currently have 120 INT at lvl 50 with base+equips, and I will have 30k clean at around 160-170. You could also MP wash, if you have base INT and spare funds - depending on how soon you want to boss.
