So I have been looking into the various 'Aspect's of the Beast' you get from the Totem Warrior Barbarians in 5e, as my own character is about to hit that level I am looking for clarification in regards to the rules associated with the wording for the 'Elk' aspect.
In the Sword Coast Adventurer's Guide, pg. 122 it states:
Elk. Whether mounted or on foot, your travel pace is doubled, as is the travel pace of up to 10 companions while they’re within 60 feet of you and you’re not incapacitated (see chapter 8 in the Player’s Handbook for more information about travel pace). The elk spirit helps you roam far and fast.
And then referring to Chapter 8: Adventuring, Pages 181-182 it states:
While traveling, a group of adventurers can move at a normal, fast, or slow pace, as shown on the Travel Pace table. The table states how far the party can move in a period of time and whether the pace has any effect. A fast pace makes characters less perceptive, while a slow pace makes it possible to sneak around and to search an area more carefully (see the “Activity While Traveling” section later in this chapter for more information).
Now does this increase movement also apply to in combat? I believe it does not but the term Travel could be interpreted into all movement. Again I do not believe this to be the case as it would then make my character's movement in Combat 90ft without dashing or spells.
