Skald

Savage Inspiration
Beginning at 8th level, your music can inspire allies to new heights of valor, whipping them into a frenzy of glory and carnage. As a bonus action, you can expend one use of your bardic inspiration to send an ally within 60' of you into a battle rage until the end of your next turn. This rage grants Resistance to slashing, piercing, and bludgeoning weapons and adds 1d4 damage to all strength based weapon attacks.

Heroes of Legend
Beginning at 13th level, you can extoll the mighty deeds of your comrades in arms, wielding tales of past heroics to drive your fellows onwards to every greater triumphs. When an ally within 60' of you scores a critical hit, you can use your reaction to give them or another ally within 60' the benefits of either Bardic Inspiration or Savage Inspiration. This does not consume a use of your bardic inspiration.

Einherjar Calling
Beginning at 18th level, you may call out to the fallen heroes of the past, throwing wide the gates of Valhalla and inviting the glorious dead to do battle once again. Once per long rest, you can use your action to summon up to three hero characters who had previously perished (and are not currently alive) over the course of the campaign. These characters arrive at locations of your choosing within 60', have full health and no expended resources, and have the same abilities and equipment they perished with. The summoned heroes act on your initiative count and cannot take any Action or Bonus Action on the turn they are summoned. The summoning lasts for one minute and requires Concentration. If you lose Concentration on this effect, the summoned heroes fade.
