Pen Nib’s First Move

Earn one jewelTumbled GarnetLevel 2

In the game Slay the Spire, the Ironclad has a relic called Pen Nib. This turn, Pen Nib doubles the damage of the first Attack card he plays. He will play Strike and Cleave once each. Use only the damage shown.

Card Normal damage
Strike 6
Cleave 8

Compare both orders in the record below. Separate paper is optional.

  1. The Ironclad plays Strike first, then Cleave. How much total damage does he deal?

  2. He still plays each card once. Can he deal more damage by changing only their order? Give the better order and total. Explain why it is better.
