Campaigns that run in the Lands of Arda, usually come with Talent Trees. Talent trees allow further character progression depending on the activities the players choose to engage.
Not every talent tree is available in every campaign, except Religion (see post below).
Each talent tree has its own point system, and acquisition of points differ per tree. Some trees are gaining points by group activities, others by individual activities. In some campaigns, some trees give debuffs (for example, Corruption tree in Bloodmoon: Vampire's Kiss campaign).
Talent trees are very new and susceptible to balance changes, especially with the new ruleset of 2024.
