Rallymaster

Lialid has stood for generations, with the gathered might of their Monarch, the Lux Crusade and the Masters of Magic, the city was a fortress that could not be breached. It withstood two separate wars, only ever being threatened by the draconic march from the south. The humans of Lialid are renowned for their adaptability and fierce fighting. Some mercenaries and adventurers would travel just to receive training in the radiant capital. Many soldiers and people within Liliad's armies are trained to be Rallymasters, wielding a magical banner that allows them to rally their allies and motivate them to preform their duty.

Only one banner can be active at any time, if you place a banner while you already have one active, the previous one is destroyed.

Imporved Banner

At 10th level, your magical banner has been enhanced. Your banner's range increases to 50ft and if it would be destroyed, you can expend an additional use of Rally to the Flag! and restore it to half your hit point maximum.

Band Together!

Starting at 15th level, you can make your allies resistant to damage while they are in your banner's range. When you place down your banner, you can choose a damage type you are currently have resistance to. The banner gains resistance to that damage type and grants that resistance to all friendly creatures within the banner's range. If you or another friendly creature already have resistance to that damage type, you are instead granted immunity to that damage type while within the banner's range.

If you grant the banner resistance to a damage type and you then lose that resistance at a later point while it is active, it retains the resistance. The resistance is only reset when the banner is destroyed or replaced.

Victory Banner!

At 18th level, you gain a magical empowerment that grants you extra strength when near your allies. At the start of each of your turns, you gain a +1 bonus to every damage roll you make for each friendly creature within your banner's range. If you leave the banner's range, this only applies for your next damage roll. Re-entering the banner's range resets this effect.
