Anti-Fear Tactics

Many raid mobs (dragons especially) have fear effects which cause

Magic Resistance

The most important thing a player can do to protect against fear is buff their Magic Resistance stat. Obviously better gear can raise MR, but buffs can also add a lot. In fact, a level 60 Bard (using a discipline) and an Enchanter can raise a character with as little as 4 MR to the maximum of 255 (see Buff Lines#Magic Resistance).

Bards

The Bard song Psalm of Mystic Shielding is by far the strongest Magic Resist buff. A level 60 Bard can give +70 MR normally, and an even more impressive +196 MR when they also use their Puretone Discipline at the same time.

Enchanters

Enchanters can cast Group Resist Magic to add 54-55 MR, and it lasts 36 minutes (unlike the Bard song which has to constantly be maintained.

Intelligence-based Casters

The four Intelligence-based casters all have a self-only buff Shield of the Magi which adds +24 mana.

Magicians

While it doesn't actually help the Magician, a Mage of level 59+ can make their pet completely immune to fear with the Valiant Companion buff. This makes mage pets more reliable DPS than even a character with 255 MR, in a fight with fear.

Null Potions

Characters can also raise the MR temporarily through buffs from the Greater Null Potion (+25 MR), Null Potion (+15 MR) or Minor Null Potion) (+5 MR).

Bark Potions

At first glance, the Bark Potion and its buff Stalwart Regeneration (which gives +2 HP regeneration/tick for one minute) doesn't seem very useful against fear. However, the buff also has a secondary effect of rooting the character in place.

This means that if a melee character uses a Bark Potion while standing next to a raid mob, they won't leave the mob even if they become feared. This can be especially useful for a tank, since it ensures that the raid mob will keep attacking them, even if they get feared, as long as they can still maintain agro.
