Becomes a mobile smithy with saddle on. Most materials weigh much less on it than with other tames. The only way to make some ascendant equiptment is with a thorny dragon with high weight. Decently collects wood and thatch ( mostly wood.) collects hide, chitin and organic polymer well. If useing as a battle tame be sure to have a good saddle equipt. Its ranged attack if used in a group can knock other players out easily. With a 2 day egg to adult period breeding can be very easy for this tame.
Put a floor on ur paracer with walls and a celling then put gate at back with ramps leading dwn stick 3 or 4 of these on back of paracer to carry say 4x 500 in carryweight of wood but a paracer can hold say 1500 only 1000-1200 will be used depending on the weight of thornys
You can knock out low levels with something as simple as the boomerang. Just try not to get hit by too many quills. One or two per barrage shouldn't be too bad. Anything beyond that could be certain death
