Team Fights

This is a very good tactic as Crystal Maiden my secret also, You blink in with blink dagger then cast Freezing Field (Ultimate), Then WHILE CASTING use Shadow Blade and you will still be casting, doing damage, slowing, etc. but you will be INVISIBLE.

1.Blink Dagger in

2.Start casting Freezing Field (Ultimate)

3.Use Shadow Blade (while casting and dont move like normal)

4.Win the team fight

Supporting?

Crystal Maiden (Rylai) is a support but can play aggresive if played right, so what i meant in the item guide (Supporting lane partner) is that if they are low on health you should buy them some things to give them the mana or health back and teleport scroll to be quicker and faster to make sure there is no ganks or tower diving, sure you dont have to buy all of it thats just an idea of what you need or could use but if your lane partner is at full health or close or something you dont have to buy it, its just giving a little bit of help on what to do if your lane partner is low on health and or mana.

Ganking

Crystal Maiden (Rylai) can be a very succesful ganker, she has two 30% slows (Frost Nova and Freezing Field) and a spell that stops movement and basic attack (Frostbite), so i would suggest coming in from behind then using Frostbite to start it off with the no movement then quickly hit with Frost Nova to slow but before Frostbite is even done you should be in close beside them and cast Freezing Field to ensure kill and do tons of damage while slowing even more, and if you have the Shadow Blade you can stealth in and get in real close then attack and start the gank while is most likely going to be a kill unless they are very tanky.

Arcane Aura

The Arcane Aura on Crystal Maiden (Rylai) is a very helpful aura, it is global which means it affects all your allies by increasing mana regen (regeneration), even by the little bit that it starts off with giving (0.5), it stacks up very quickly and may even get someone a kill just in time because they needed the mana, help them escape, or just help a hero that has mana problems like earthshaker who is almost out of mana in one spell early game, overall i think Arcane Aura is a very helpful aura and is a 10 on my scale.
