Level 15-21 Thorns Aura When Equipped
Thorns is one of the Paladin’s Offensive Auras. Any monster that causes melee damage to either you, your minions, or any of your party members within the range of the Thorns Aura, will have that damage returned to them several folds.
The Necromancer who has minions will benefit from this Aura, but it would only be effective with Golem or Revives, as Skeletons die too easily, especially in Nightmare or Hell Difficulties.
It might appear to be good mod at first, but the damage returned by the Thorns Aura is small compared to the disproportionately large amount of hit points possessed by the monsters in Nightmare and Hell Difficulty.
+50% Faster Hit Recovery
+50% FHR is massive, and great for melee fighters who require more % FHR to break their target breakpoint.
The more Faster Hit Recovery % your character has, the quicker he/she will be able to break out of the stun animation when they get hit. The quicker your characters recovers from an attack, the quicker they can retaliate (or run away).
+25-50% To Poison Skill Damage
Necromancers using Poison Nova consider this mod the main attraction behind the Bramble Runeword. The only drawback to this mod for them is that the bonus spawns with quite a variable value, with near-perfects (45% and above) being very sought after by the community.
Increase Maximum Mana 5%
Regenerate Mana 15%
Sorceresses can put points into Warmth, a Fire Skill that improves their Mana recovery rate., Unfortunately Necromancers do not have a similar skill, but this is rectified by mods such as Regenerate Mana, which can go quite a ways to helping them recover Mana quickly so that they can unleash more Poison Novas upon the denizens of Hell.
+5% To Maximum Cold Resist
The default maximum for Resistances is 75%. Certain unique items (like with the Bramble Runeword) can boost the maximum Resistance up to 95%.
Fire Resist +30%
Poison Resist +100%
The Bramble Runeword offers a healthy boost to Fire Resistance, and a whopping +100% to Poison Resistance. Wearing body armor with the Bramble Runeword, Poison Nova Necromancers would need only a small Poison Resistance boost from other items to max out this Resistance.
Summary:
Bramble doesn’t offer a lot to most classes and builds, except for perhaps the large boost to Poison Resistance. For Poison Nova Necromancers, however, it is a viable option for them to consider.
