Power Banner

The Power Banner is a craftable Hardmode Summoner Banner. On use, it summons a banner that grants the player the Power Banner buff while within proximity of it, indicated by an orange ring around it. The buff causes the nearest sentry to the player—indicated by a star on top of the sentry—to deal an additional 50% summon damage.

As with all summoner banners, only one can be active at a time; using another one will cause the Power Banner to vanish.
