Handy calculators for Last War: Survival — free to use, no account needed.

Hero stars, exclusive weapon levels, and Tactical Drone levels all use resource costs that scale up sharply the further you go — spending shards, Battle Data, or Drone Parts without a plan often means over-investing in one hero or system before you've covered the basics across your whole roster. These calculators use the game's real cost tables so you can work out exactly what a given upgrade needs before committing resources, then compare that against what you actually have on hand.
