Blue Resin

Uses
As a common type of Resin, Uncorrupted Blue Resin is the one resin type that Owen begrudgingly accepted amongst the Season 1 Cast. The healing Blue Resin provides is efficient, as it is slow, meaning that it can only be used outside of combat scenarios. This made is invaluable to any travelling group, as its ability to heal damages to the body and regenerate the flesh for seemingly no cost made it seemingly very powerful. Although there is in fact a limit to how much Blue Resin can heal. Poisons, conditions afflicting the mind, and corruption cannot be healed through this power.

Corrupted Blue Resin wasn't seen very often, and thus its abilities were never seen in-universe. It has a slow-drain effect that overcame any resistances, but no longer had any healing properties. As with all Corrupted Resin, they have a negative effect on all races par Half Druids. Exposure to Corrupted Blue Resin will eventually cause a crippling pain on your own body as you drain away someone else's. Eventually, the damage you sustain will outweigh the damage you deal to an opponent.

Embedded
Having an entirely supportive-based Resin Crystal on a weapon is probably not a great idea, as a passive enchantment would restore some of the damage done with the weapon. An active enchantment would act as a normal Resin Crystal would.

Enchanting Armour and accessories, however, is where the true power of Blue Resin comes into effect. It can provide a passive heal-over time effect as if you were constantly under the influence of a healer. But in doing so, would make you much more susceptible to Corrupted Resin-based attacks.

Ultimate
Although it was never shown, by crushing a Blue Resin Crystal, the healing energy that encapsulates Blue Resin is released in a nearby area. It will immediately heal (within the limits of Blue Resin) everyone within a short radius of the user. The healing given is split between the amount of people in the radius.

Trivia

 * Corrupted Blue Resin was the first type of Resin revealed to have a corrupted state. It was also the type of Resin Crystal used to contain a Vessel of Corruption.
