First cast at 9.25 s with 0.80 attacks per second. Items, traits and damage taken change the mana pace; the cast, effect and channel windows do not.

Step by step, in words
  1. Mana reaches 70/70: the cast starts and the mana lock goes on (no mana from attacks, ticks or damage taken).
  2. 0.00 to 2.00 s: cast window. The unit plays its cast animation and its return to idle; it cannot auto attack.
  3. 0.70 s: the ability's effect fires (projectile launch, damage, shield...).
  4. 2.00 s: unlock. Mana starts again (overflow kept) and a fresh attack starts from zero; it lands at 2.15 s at base attack speed (the attack delay is 12% of the attack animation).
  5. Attack loop: the attack lands at 12% of the attack animation (mana granted) and unlocks at 40%; a cast that becomes possible at the landing starts at that unlock point, cutting the rest of the attack.
  6. Mana gain: 7 per attack and 2 per second; combat starts at 0/70.
  7. Overflow is banked: mana past 70 from attacks or regen is kept through the cast (68/70 plus 7 casts and comes back with 5). Same rule for every champion; only the amounts differ by role.

// Itemized Roles

Ranged AP CarryPrimarySpear of ShojinRabadon's DeathcapJeweled Gauntlet

5-cost ranged AP Caster (game role tag, range 5). As the comp's damage dealer it takes the best calculated damage items. Mana lock 2.00 s per cast against a 9.3 s fill (18% locked). Casts per minute at base speed 5.3; with Spear of Shojin 7.8, Blue Buff 7.9, a +45% attack speed item 6.7. Blue Buff and Spear of Shojin are within 1% of each other, so either keeps the loop rolling; the default mana-per-attack set stays.

Ranged AP SupportSolidVoid StaffRed BuffSpear of Shojin

5-cost ranged AP Caster (game role tag, range 5). When another champion carries, it holds the team Shred/Sunder and Burn items. Mana lock 2.00 s per cast against a 9.3 s fill (18% locked). Casts per minute at base speed 5.3; with Spear of Shojin 7.8, Blue Buff 7.9, a +45% attack speed item 6.7. Blue Buff and Spear of Shojin are within 1% of each other, so either keeps the loop rolling; the default mana-per-attack set stays. For supports with quick casts: Void Staff spreads Shred, Red Buff adds Burn and Wound, and Spear of Shojin accelerates the short casts that deliver them.
