Ice and Dragons

Ice and Dragons is the tenth challenge on the Change of Heart board. It consists of defeating a quartet of DragonLord Vilmor and Cryozen and Dragonmaster Frostscythe and Glaisaurus at the same time.
== Rules ==
=== Global ===
# If using DragonSlayer, both Vilmor and Frostscythe will enrage, each automatically inflicting a separate 10% Null DoT (28.43% total due to their DEX) every turn, effectively banning the class from the fight.
=== Cryozen ===
# Cryozen starts each rotation with a -Ice debuff that grows stronger every time he tries to inflict it (-5, -20, -35, -50, etc) that also reduces healing.
# Cryozen has a 4-hit stun as part of his rotation.
# Cryozen applies a 25% damage regeneration effect to all four members. Beware of using -All effects that don't inflict +Health!
# Defeating Vilmor grants Cryozen an additional +75 Bonus and +75 Boost, making it extremely difficult to avoid his -Ice debuff.
=== Vilmor ===
# Vilmor gains MPM and BPD, Bonus, and Boost on rotation, reducing the effects of damage mitigation.
# Vilmor inflicts a large DoT at the end of her rotation, and uses a much stronger version of that attack below 50% HP.
# Vilmor gains 10 All for each effect the player has active, positive or negative.
# Defeating Cryozen grants Vilmor an additional +75 Bonus and +200% Boost, further reducing the effects of damage mitigation.
=== Glaisaurus ===
# Glaisaurus inflicts a -Ice debuff on rotation, making him an extremely disruptive threat, as it cannot be reliably glanced with BPD.
# Glaisaurus applies a +50 Bonus and Crit buff to all enemies, further reducing the reliability of shields.
=== Frostscythe ===
# Frostscythe gains 10 All for each effect he has active, excluding itself.
# Frostscythe spends three turns applying random debuffs, before using an Ice nuke that grows stronger every time it is used.
#* Said nuke may also be empowered depending on which debuffs he tries to inflict (regardless of whether or not they were successfully inflicted), becoming an autocrit with +200 minimum Bonus, and potentially dealing even more damage and having +300 Bonus.
== Turn Order ==
Cryozen -> Vilmor -> Glaisaurus -> Frostscythe
== Equipment ==
As the fight is balanced around extremely high resistances, the following gear maximizes your Ice + All resistance without the need of DC/Seasonal gear:
* (0+10) Exalted Apotheosis (or any +10/-20 Inn Weapon)
* (0+15) Wings of The Thousand Flames
* (10+0) Frostbreaker's Ring V
* (13+2) Void Rift Cover
* (15+0) Refraction Pendant VII
* (0+4) The Corrupted Seven
* (0+10) Grimoire of the Lich/Ourobouros Root Belt
* (0+1) Legion Bracer (or any of the Epoch Artifacts)
Total: 80 Ice + All, along with ~99 Immobility + All to deal with Cryozen's stun. 
* Diamond Ring of the Emperor is also recommended if not shielding Cryozen's stun, as it pushes Immobility to 100 at the cost of -2 Ice that turn with Apotheosis.
* If not using Apotheosis, Ultra OmniKnight Blade is recommended to swap to in order to achieve Stun immunity.
If DC Monthlies and DM gear is available, the following set provides better stats:
* (0+10) Exalted Apotheosis
* (0+15) Wings of The Thousand Flames
* (10+0) Frostbreaker's Ring V
* (10+5) Winter's Harbinger IX
* (15+0) Refraction Pendant VII
* (0+5) Elemental Unity Defender XV
* (0+10) Grimoire of the Lich/Ourobouros Root Belt
* (0+1) Legion Bracer (or any of the Epoch Artifacts)
Total: 80 Ice + All, along with ~100 Immobility + All.
Additionally, an anti-dragon weapon is highly recommended for bursting the dragons down, as they are the larger threats with their -Ice. Vile Infused Rose is helpful for dealing with Vilmor and Frostscythe, but isn't as important.
== Strategy ==
Due to the sheer volume of rotations and attacks to worry about, a 99-turn rotation of the fight has been documented.
* For classes without a low CD MPM shield, the kill order is Glaisaurus -> Cryozen -> Frostscythe -> Vilmor.
** Frostscythe is prioritized over Vilmor because his debuffs make her <50% phase significantly tankier due to 'Against the Odds' as well as directly debuffing your offense.
* For classes with a low CD MPM shield, the kill order is Glaisaurus -> Frostscythe -> Vilmor+Cryozen
** You can avoid Cryozen's -Ice forever with a 1/5 or 2/6 MPM shield, as long as you have a 200 Protection Dragon.
** Try to kill Vilmor and Cryozen at the same time to avoid dealing with the enraged survivor.
* The first -Ice from Cryozen can be comfortably ignored, but future instances of the debuff should be avoided or purged ASAP.
== Classes ==
* Kathool Adept is unsurprisingly the best class to use in a fight where shields matter, as Writhe lines up perfectly to avoid all of Vilmor's nukes, along with Cryozen's nuke, stun, and -Ice. In addition, thanks to the relatively low HP of all four bosses, Kathool (relatively) quickly ends the fight.
* Ranger is one of the best free options as it has a shield uptime for 4 turns in addition to big damage from offensive gearswapping in order to deal with the 4 enemies with relative ease. 
* Technomancer is also a good free option. It has a good shield uptime in addition to great damage in order to deal with the 4 enemies with relative ease.
