A burst of damaging frost slows enemy movement in the targeted area.
Abilities, roles and builds with an explanation for every purchase.

HERO GAME PLANWe provide mana for the team, hold targets with Frostbite and choose a safe window for the ultimate.
Able to keep her allies supplied with mana as she slows down enemies to ensure a kill, Crystal Maiden is a helpful addition to any team. And, when the opportunity arises, she can unleash her massive ultimate ability to devastate her foes.
My recommendation is a starting point. We choose another position together with the team and for its needs.
Help the lane, provide vision and keep the ally alive first; expensive upgrades follow the necessary team purchases.
I contribute through laning, control and movement. I adapt the expensive core route to my budget.
I compare my starting point with current high-MMR builds. I name the source beside the build path and choose my own variations for the match’s needs.
The core from the current Dota2ProTracker sample is Tranquil Boots, Shard and Blink. I add Glimmer as a situational save; I choose BKB and Aghanim for the specific fight.

Provide speed and regeneration between engagements, fitting a support’s budget.

Unlocks or upgrades Crystal Clone. The exact effects are shown below in the abilities section.

Changes the entry angle and lets me reach a target quickly. Damage taken can prevent its use.

Adds a protective tool and hides the chosen ally; invisibility does not replace escaping detection.

I do not assign one ‘correct’ minute to every purchase. I look at my gold, the next fight and the problem: am I missing mana, target access, control or protection? If an expensive slot will arrive too late, I get a useful answer earlier.

Allows movement, attacks and spellcasting while the ability is active. Enemies can still interrupt it. The hero moves 75% slower. Increases the number of explosions by 20%. Units affected by the ultimate for more than 3 sec. receive Frostbite.
These abilities are not necessarily available at the same time. I check the condition beside the name: innate ability, another form or an Aghanim purchase.

The hero slides in the chosen direction, disjointing incoming projectiles and leaving a crystal clone at the previous position.
