Sunheart Bloom

The attack routine runs on a one second tick. Each tick raises the plant's lifetime counter by one and lowers its attack counter by one; when the attack counter runs out the plant attacks and the counter is reset. The reset is a constant 4 compiled into the routine, and the counter starts at 2, so the first hit is the second tick and every hit after it is 4 ticks later.

Where it lands: The damage is figured from the summoner's Magic Attack: the plant is a building and carries no stat block of its own.

When it runs: Every second the plant stands, from the moment it is summoned until it crumbles.

What it applies to: Every hit the plant makes while it stands. The cadence is driven by the routine's own counter, not by a skill cooldown.

Worked numbers

Hits landed by that moment.

Rule of thumb: Every 4 seconds it stands is one more hit, with the first at 2 seconds.

Things the tooltip does not tell you

• The 4 second cadence is in neither the tables nor the in-game description: the reset is a constant compiled into the attack routine, so no data change can move it.
• The attack counter starts at 2 rather than at the interval, so the opening hit comes twice as fast as the ones that follow.

How it interacts with other effects

• The Critical Weakness a hit applies runs out before the next hit arrives 4 seconds later, so a target is exposed in bursts rather than for the whole time the plant stands.
• It hits harder per attack than Solar Bloom but fires four times less often, so a Solar Bloom puts out more damage per second; what this plant buys is the wider hit and the Critical Weakness, not a faster rate.
