Allied Supply Crates

The Allied Supply Crates, located in the Party Camp, allow the Warden to invest resources in the equipment of the allied army that will eventually battle the Blight.

Interaction
If the Warden has the appropriate items in their inventory, interacting with the crates opens a menu where a number of investments can be made. Depending on the path taken through the game, emissaries of the various factions will be standing near the supply crates. The Warden can tell them to be ready and glean hints about what kind of items they require.

Effects
Investing resources into the various factions (where applicable) should apparently result in improved equipment and abilities for allied troops, but the mechanics and actual effects of this system are unclear. Even though numbers and upgrades from donations are unclear, with enough donations emissaries will say different lines depending on how much you donate. For example the mage emissary will say something like "Such power has not been seen since..." and after more donations of runes he will say "Even the templars will be amazed...". Whether or not this is just a morale booster for the player to donate more or actually indication of more power is unknown.

The most likely possibility is that as enemies scale with the Warden's level and that level can increase dependent on the quantity of donations. The troops will scale in power too, at the same rate as their equipment, as the higher the Warden's level is the higher grade equipment the human emissary wears.
