Reaper Form -This provides bonuses to swing speed,
spell damage, and resists. However, while in this form, the caster is susceptible to fire and moves at a slower speed.
Wildfire -A blast of intense fire inflicts fire damage on all opponents within its area of effect. Lasts for several seconds.
Essence of Wind -A blast of cold air inflicts cold damage on all enemies within its area of effect. Enemies attack and cast spells slower while under this spell’s chill effect. Chill effects last for several seconds.
Thunderstorm - A thunderous boom temporarily smites opponents with energy damage and
may reduce spellcasting recovery time for the duration of the spell
Ethereal Voyage -Allows the arcanist to wander around in an ethereal form as if under the effects of monster ignore. Effect ends after the duration expires or when the caster performs a hostile action (whichever comes first). The arcanist is still visible to other player characters and may be attacked by other player characters as normal. Cannot be used during the heat of battle; also cannot be used while in other forms, such as vampire form.
can be used to tame aggressive pets similar to honor tame.
Word of Death -This spell can possibly slay any one creature (not players) that is under 5-30% of its maximum health. Creatures that are not slain outright take chaos damage instead. Creatures that are under 5-30% of their health take direct damage. A few notable creatures are immune to Word of Death: Harbingers and
Slasher of Veils.
Gift of Life -Death during this spell effect can possibly be reversed for the arcanist or a bonded pet under her control. If the caster or a bonded pet dies while under the effects of this spell, then she/it is instantly resurrected, restored to 50% health, cured of all poisons, and the spell ends. Only the arcanist and her bonded pets may be resurrected in this manner. Can be really useful when a peerless run goes bad
Arcane Empowerment -For the duration of this spell, the caster’s damaging spells (Does not exceed 15% PvP SDI cap)
and healing spells are increased in effectiveness. Summoned creatures and animated undead are also increased in effectiveness. Quite useful when you are dealing with a heavy damaging mob.
Attunement -The arcanist becomes one with an enemy’s weapon. Creates a magical barrier absorbing Melee Damage.
Example: Spellweaver with 100 skill, No Arcane Focus: 45 points of damage absorbed for 60 seconds,
with Level 6 Focus: 81 points of damage absorbed for 132 seconds.
Gift of Renewal -Increases the recipient’s natural health regeneration for the duration of the spell. The added benefit of heals can often times help a mage keep up with the healing of a pet when it is being hit hard.
I have found all the above quite useful at different times.
