Spawns a column of expanding fireballs. Called by LichAttack, but also available separately.
Shoots an IronLichShot3 projectile. Its frame will be set to S_LICHFX3_4 and the ht_hedat1 sound will be played. Five more similar IronLichShot3 projectiles will be spawned at the same location, but their frames will NOT be set to S_LICHFX3_4, their damages will be set to 0 and their 0 counters set to 2, 4, 6, 8 and 10. Subsequent calls to LichFireGrow from the projectiles will displace them, reset their damage and put them in S_LICHFX3_4 at a delay according to the 0 counter.
