Frost has high base armor and excellent shield values and can be played as either an offensive bruiser caster or a defensive tank support . An offensive Frost can focus on abilities such as Ice Wave and Avalanche to slow and clear entire rooms and waves, or use Snow Globe and Freeze for a more defensive role by protecting teammates from gunfire and immobilizing powerful enemies, respectively.
His base sprint speed is amongst the slowest of the Warframes. Keep this in mind when dealing with impatient team mates playing faster frames or when running from fast-paced enemies such as disgruntled Infested or Corpus Moa. Adding a sprint speed mod (Rush) of 20% or more is usually considered enough to keep up with other players and reduce the frustration from such a slow base speed. Advanced players may use the "Horizontal Kick-Off" Maneuver to catch up to teammates.
Its primary strength is that a direct hit causes the target to be frozen in place for a fixed 10 seconds, regardless of rank. This is particularly useful when fighting single enemies such as bosses to buy time for teammates to revive incapacitated Tenno, recharge shields, reload, etc.
Targets that are frozen will be freed of their immobility if they take health damage by anything. Freeze's utility can be easily wasted unless proper coordination with teammates is exercised.
Freeze can be used to set up an effective kill-combo on an enemy with a burst-damage attack.
As a damage and crowd control ability, it can be dependent on the situation; it only affects those in front you rather than all around you. It works effectively against a large group of enemies rather than a single enemy like a boss.
Even though the wave moves along the floor, it is able to hit enemies that are slightly above or below it, such as Shield Ospreys.
Ice Wave is best used against enemies in a tightly-packed line. Loses effectiveness on infested as Ancients resist much of the damage.
Since it passes through Snow Globe, Ice Wave can be used to clear the globe of enemies if Frost is somehow forced out of it.
Enemies that enter or are already inside the snow globe will suffer the Cold effect, though their bullets will travel normally when fired inside the shield.
Those inside the globe can shoot targets outside, however players outside the globe cannot shoot targets inside; the globe blocks all incoming fire, enemy and player alike. Using a snow globe to trap and slow down a boss is best recommended for an organized team, as players some distance away will have their ordinance blocked by the globe.
The probability of being shot at when inside the shield is lower when fighting Grineer Lancers and Corpus crewmen, as they tend to melee when close to players.
Creative use of Snow Globe when on the run can be used to block incoming gunfire and slow down chasing enemies.
The Snow Globe can also be used as a way through Corpus lasers. Frost's shields will still take a hit, but you'll be able to get through without being staggered or knocked down.
This ability is perfect for the defense of any fixed location such as cyropod defense missions against Corpus or Grineer, as you can use it to slow a group of enemies closer to the pod and block their fire from the outside.
There is a bug where using Snow Globe displays 75 energy is used however only 50 energy is spent upon using this ability
When against Infested, Snow Globe is best placed at choke points or around but not directly on top of the cryopod. Their tendency to swarm means that a huge number of infested enemies will quickly be trapped in the Globe making them infinitely easier to kill rather than letting them swarm the pod before they are slowed.
Avalanche stuns and knocks back enemies a small distance when cast, this may result in them being out of range for the freeze and subsequent damage, so it is important to make sure you group enemies effectively before casting.
This ability can damage enemies through walls. Using Avalanche while pressed against a wall can clear a room without even entering.
Avalanche can hit enemies who are above or below Frost's position.
Scales well against Corpus as freeze does double against shields, useful for destroying Corpus being protected by shield Ospreys.
