Red Resin

Uses
Red Resin, being the most common type of Resin, has been used frequently throughout the multiple seasons. Despite its commonality, the destructive capabilities of Red Resin and Fire Magic outweighs several rarer forms of Resin. Although it can be used defensively and has some utility, the true power of Red Resin shows in its offensive styles.

The corrupted variant of Red Resin was only ever used by Vampires, in which they were able to use their own blood (or someone else's) to either create objects or use solely offensively. It retains its destructive capabilities, but the range of which Corrupted Red Resin can manipulate Blood is very short. As with all Corrupted Resin, they have a negative effect on all races par Half Druids. Exposure to Red Resin will start a painful, and painstakingly long transition into becoming a Vampire, although you will immediately turn into one should you be a Revered Soul with a Corrupted Red Resin crystal.

Embedded
When embedded into a weapon, a passive Red Resin enchantment would give the weapon an extra punch and would burst into flames on-hit. An active resin enchantment would allow for all the properties of a Resin Crystal, but on a weapon, flavouring all Resin-based attacks to be coming from the weapon.

Having a primarily offensive Resin Crystal embedded into armour is probably not a great idea, but can give resistance to Fire-based attacks.

Ultimate
Although it was never shown, by crushing a Red Resin Crystal, an individual would be able to coalesce the latent flame inside the Red Resin Crystal for one tiny ember of flame. Upon connecting, a pyroclastic eruption of flame would burst into the sky- torching and incinerating the entire area around it. The damage of this attack would decrease the longer the Resin Crystal's existence. For the most damage, an individual would have to crush the Resin Crystal as soon as it was made.

Trivia
