Artifact upgrade cost calculator
Choose the piece, its star rating and the levels you want to go between. The calculator adds up the silver using the game's own upgrade tables. Every attempt costs silver, and a failed attempt costs the same as a successful one, so the real total depends on luck. The figures below are an estimate, not a promise.
Your upgrade
Needs JavaScript. The full table of silver and chances is below.
How the numbers are worked out
- If every attempt succeeds adds the silver for one attempt at each level. It is the least you can spend.
- Average total adds up silver per attempt divided by the chance of success at each level, which is the long-run average.
- Typical, unlucky and very unlucky runs come from 100,000 simulated upgrade runs with fixed settings, so the same choices always show the same figures. They are rounded to three digits because a simulation is not exact.
All upgrade costs by star rating
Silver for one attempt at each level, and the chance that attempt succeeds, as listed in the game data (game build 11.85.5). The same silver is spent whether the attempt succeeds or fails. Weapons, armour and other non-accessory pieces:

What has and has not been checked
The figures were compared with the game on three non-accessory pieces (6-star Mythical helmet, 6-star Legendary shield and 5-star Mythical shield) and on one accessory (a 6-star Mythical ring). At every level from +0 to +15 the silver and the chance label matched this table, on both 5-star and 6-star pieces and on both Legendary and Mythical, and the slot made no difference. +16 was the highest level seen on 5-star and 6-star pieces. Star ratings 1 to 4 come straight from the same game table and have not been checked in the game, and the game data does not give their highest level, so check the maximum for your piece in the game. Only a ring was checked among the accessories; amulets and banners use the same table in the game data but were not seen. Instant upgrade is described by the game as using the same silver and the same chance as upgrading by hand.
