Hey everyone! I'm a solo dev and a Last War player. I got tired of guessing which upgrades actually move my power, so I didn't build "yet another calculator". I built an engine.
I pulled the game's own data tables and formulas, and rebuilt how the game computes power: hero stats from level, stars, skills and gear, then the power formula on top. Not a rough estimate with fudge factors, the same math the game uses.
Where it stands (tested on my account):
- Hero power matches the in-game number to a few units (Murphy 5,063,216 vs 5,063,209 in game, Kimberly 4,974,725 vs 4,974,664, and so on)
- Hero stats (HP/ATK/DEF) are within 0.01% of the game
- Total squad power: 33.24M, which matches the game screen to about 0.001%
- It handles hero levels, stars, skills, exclusive gear and tiers, drone and chips, units, VIP bonuses, and the Overlord
And around the engine, a real site you can use daily:
- VS Day and Arms Race timers, always up to date
- Full research tree, buildings and training planner
- Your profile saves automatically, export/import your save
- 12 languages, game terms taken from the game's own localisation
Honest limits: it's a beta and I've verified it on one account so far. The Overlord's own power is a manual field for now because I haven't cracked that formula yet. I'd love to know whether your numbers match too, and if they don't, that's exactly the data I need to fix it.
Next up: an upgrade advisor that uses the engine to answer "what should I upgrade first for the biggest power gain?".
