Intro Sprint Card

Fully Upgraded Intro Sprint Card

Wave increases by x10 each time for a number of waves but reduces coins by 80%. Locked, cannot be unequipped in the run.

Use

Intro Sprint Card allows the earliest levels to be skipped at the cost of most coins earned from both kills and waves.

When Intro Sprint is activated you will complete 10 Waves isntead of 1 and the boss will come on the first wave. Although if the Tower takes any damage (wall excluded) its effect will end even if you have more waves that can be skipped.

Bosses can’t drop modules or reroll dice while it is running. Wave Skip will not activate. Wave Skip, Wave Skip, Missile Barrage and other activated skills cannot be used during the sprinting phase.

Might be useful for some missions and challenge like Death Defy Event missions in order to sprint the highest tier stage, get defeated and try again. That allows more attempts to trigger death wave in the shorter amount of time.
