Maxing an Invoker means ascending to 6★ (level cap 60) and Awakening to level 6. What each rarity costs, with Echoes or with food Invokers.
Ascending to 6★
Level the Invoker to its cap, then feed it Echoes or Invokers of its current star. Going 5★ to 6★ takes five 5★ Echoes or five 5★ Invokers of any rarity.

Building food from 1★ Commons
Echoes mostly come from packs, so food Invokers are the usual route. Starting from 1★ Commons only, each step's food costs:

A Legendary from 5★ to 6★: 600 Commons, 12,664,000 XP and 850,000 Gold to build the five 5★ food, plus its own 600,000 Gold.
XP and Gold are for levelling and ascending the food. Food itself is fed at any level.
Spare higher-rarity Invokers skip steps. Used as food, a 3★ Rare saves 6 Commons, 66,000 XP and 3,250 Gold; a 4★ Epic saves 24 Commons, 418,000 XP and 28,000 Gold.
Estimated: assumes food can be any level and ascending keeps the Invoker's level.

Echoes are spread across the steps (for example 1 + 2 + 3 + 4 + 5 from 1★). The Invoker's own levelling to 50 adds 1,618,300 XP either way. How much levelling and Awakening each add: Levelling vs Awakening.
Awakening to level 6
Each Awakening level needs that star reached (level 6 needs 6★). Costs depend only on rarity: two Legendaries pay the same. Runes match the Invoker's faction, Essences its element, Crests its class.
Awakening also unlocks accessory slots and can extend how long your Titan's Invokation lasts.
Awakening types
Every Invoker has one of 8 Awakening types. It sets the Invoker's built-in ratings and what each Awakening level's 11 nodes give. Percent bonuses are of the Invoker's 1★ level 1 HP, ATK and DEF.
