Cartographer's Quill

Cartographer's Quill is a relic in Wizard of Legend.

Description
Increases damage by 0.04% for every one percent of the map covered for a maximum of 4% on a fully completed map. All damage increases are cumulative, last for the duration of the run, and will not be reset when dropped from the inventory.

Strategies
To fully utilize reveal 100% of the map on each stage (e.g. 1-1, 1-2, etc.), in order to gain the full 4% damage increase available from every floor (excepting boss arenas as they neither add nor subtract from the total cumulative damage bonus).

Item combos

 * reveals the entire floor, providing an automatic 4% increase per floor.

Additional notes

 * This relic doesn't seem to have a cap to how much it can grow so if you are planing to go endless this relic is just plain amazing as you can make it go past 100% more damage.
 * Prior to V1.123 would reset its damage bonus when dropped on the ground.
