Lich/Guide

General
focuses on mana to support his allies, so investing on Intelligence is important for usage of abilities, extra damage, and mana.


 * Frost Blast is a slowing damaging spell used for harassing and dealing with creeps, and is more effective when used on a hero close to a group of creeps. This is 's only AOE damage-dealing spell, so paired with it can be a good farming spell.
 * Frost Blast only deals damage at a small area, so is really good for using it repeatedly.
 * Frost Blast doesn't deal much damage, so use it for creeps or for chasing enemies.


 * Sacrifice is used mainly for obtaining mana. This can give Lich an advantage so that he doesn't have to focus on mana regen, although increasing max mana is also important for Lich to make this ability more effective.
 * Use Sacrifice for fueling Chain Frost, as it gives good mana.
 * Use Sacrifice on a high health creep, because obtained mana is based on HP or hitpoints.

A good support spell, Ice Armor can protect buildings and heroes, giving them resistance to attacks.
 * When the Glyph of Fortification isn't available, Ice Armor can give some bulk to towers and buildings.
 * Ice Armor can be used on squishy heroes too for some defense, or, even better, to provide additional resistance for bulky heroes.

Chain Frost is a massive damage-dealing, slowing, multi-target nuke. It is very fatal when bouncing between enemy heroes, doing massive damage and slowing them.
 * Chain Frost is most effective when used on a group of enemy heroes with on  because this removes the limit of bounces, making it a very dangerous orb of frozen death, enabling him to do a one-on-five fight.
 * Abilities that trap or disable multiple enemies sync well with Chain Frost, because this allows Lich to not worry about enemies separating far enough to surpass the bounce range.
