Module:Heroes BoonBane

For use on the stat templates of Fire Emblem Heroes playable characters.

level1

Outputs a hero's level 1 stats, adjusted for boon and bane.

{{#invoke:Heroes BoonBane|level1|<base stat>}}

Enter the hero's base stat in the first parameter.

Example: Tana's base Speed at 5★ is 10, so the entry is as follows:

{{#invoke:Heroes BoonBane|level1|10}}

This outputs: 9/10/11

level40

Outputs a hero's level 40 stats, adjusted for boon and bane.

{{#invoke:Heroes BoonBane|level40|<base stat>|<growth points>|<rarity>}}

Enter the hero's base stat in the first parameter. Enter their growth points in the second, and their rarity (as a number) in the third.

Example: Leon: True of Heart's base defense at 5★ is 8 and he has a 50% growth rate in defense, so the entry is as follows:

{{#invoke:Heroes BoonBane|level40|8|50|5}}

This outputs: 26/30/33
