Calculate THE TSUNAMI GAME Severity costs

To calculate Severity costs in THE TSUNAMI GAME, enter your server's current reading and your target. The calculator uses the community shop's 0.5-step prices. It shows an upward change that reaches or passes your target, or a downward change that reaches or goes below it.

Example: 1.0× → 2.5× costs 15 Tokens, using +1.0 and +0.5. It is not a fixed fee: 2.0× → 2.5× costs 5, while 3.0× → 2.5× costs 2 to lower the value.

Plan the purchase

Use the live server reading. Inputs from 0 to 1,000 are supported; this is a calculator limit, not a game cap.

15 TokensIncrease by 1.5× → reach 2.5×

Buy +1.0 once and +0.5 once.

Severity shop prices

Increase Token cost Decrease Token cost
+0.5 5 −0.5 2
+1.0 10 −1.0 4
+2.0 20 −2.0 8
+4.0 40 −4.0 16

The listed buttons do not offer a bulk discount. Buying +1.0 costs the same as two +0.5 purchases. Increasing and decreasing have different prices, so reversing a purchase does not refund the Tokens you spent.

How to use the Total Severity shop

  1. Read the live Severity sign and record the starting value.
  2. Open the Total Severity shop. Check that its prices match the table before committing.
  3. Choose a target for your task. The September Secret route uses 2.5×; a higher number is not a verified guaranteed drop rate.
  4. Follow the calculated buttons. Each click spends Tokens and changes the server immediately according to the community NPC guide.
  5. Recheck the live reading after buying. Another player's purchase can make your original plan stale.

If your reading is 2.57× and you target 2.5×, one −0.5 button would produce 2.07×. The calculator shows that overshoot; decide whether you actually want the change. If you are following a route that asks for at least 2.5×, keeping 2.57× may be preferable to lowering it.

What Severity can and cannot tell you

Severity is a visible server setting, not a hidden personal score. The community describes it as affecting event frequency and rare-item chances. The sources do not provide a validated probability curve, and a wiki “weight” field is not automatically a true spawn percentage.

This calculator answers how many Tokens the listed buttons cost, not “how many minutes until a Secret” or “what is my drop chance.” A smaller server also has its own rare-item limitation in the official description. Read the full Secret setup.
