First cast at 35.27 s with 0.55 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 100/100: the cast starts and the mana lock goes on (no mana from attacks, ticks or damage taken).
  2. 0.00 to 0.91 s: cast window. The unit plays its cast animation and its return to idle; it cannot auto attack.
  3. 0.91 s: unlock. Mana starts again (overflow kept) and a fresh attack starts from zero; it lands at 1.27 s at base attack speed (the attack delay is 20% of the attack animation).
  4. Attack loop: the attack lands at 20% 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.
  5. Mana gain: 5 per attack; combat starts at 0/100.
  6. Overflow is banked: mana past 100 from attacks or regen is kept through the cast (98/100 plus 5 casts and comes back with 3). Same rule for every champion; only the amounts differ by role.

// Damage calculation

Measured at 2 stars on a level 8 board the Trait Explorer builds around its traits (optimal tall, its traits at their lowest breakpoint, teammates at 2 stars without items, positioned by role), against a level 8 enemy comp (Elderwood Lux, Ornn, Xayah, Alistar, LeBlanc, Hecarim, Ezreal, Gnar: 3 tanks, 1 melee, 4 ranged, 2 stars), over 20 seconds of combat with real cast times, mana lock and item effects.

Its board: Rek'Sai, Blossom Lux, Karma, Yorick, Yunara, Azir, Ahri, Sett.

// Itemized Roles

Main TankSituationalWarmog's ArmorGargoyle StoneplateSpirit Visage

1-cost AP Tank (game role tag). Tanks take the frontline item set. Mana lock 0.91 s per cast; tanks fill mainly from damage taken (1% of pre-mitigation and 3% of pre-shield damage per hit, capped at 50), so the lock length matters more than item mana. The classic main tank trio: a huge Health pool, resists that grow as more enemies focus the tank, and healing amplification to stay standing longest.

Main Tank picks can also serve as a Support Tank, holding debuff auras on the carry's side of the board.
