ON DEFENSE · Catalyst
Infection tower
Hits add Pollen; at three stacks, the marcher is poisoned for 3%/6%/10%/20% max health per second for 4s.
THE FIELD NOTES · CRITTERFRONT
Brood on the march. Catalyst at home. Get to know both sides of this creature.

Pollen belongs to Brood on attack and Catalyst on defense. Buying one family gives you both combat forms.
Pollen needs three hit stacks before its poison activates. Consider whether your damage coverage keeps a target in reach long enough. Its marcher's final-death effect reduces nearby tower attack speed, making the location of its defeat significant.

Catalog attack values can remain nonzero when an ability disables normal attacks. Attack × APS is not a damage forecast. Ability effects, stars, synergies, resistances, and round modifiers change combat outcomes.
2 families: each defeated non-summon marcher hatches one temporary Broodling. 4 families: it hatches one additional Broodling. 5 families: it hatches one further Broodling.
2 families: qualifying Catalyst buffs or debuffs echo to one additional target. 4 families: they echo to two additional targets. 5 families: they echo to three additional valid targets instead.
These are shared-synergy options, not a tested win-rate ranking. Only distinct deployed families count; bench units and summons do not add members.
Two matching copies at the same star merge into the next star. Stars I, II, III, and IV represent 1, 2, 4, and 8 copies. Health scales by 1×, 1.7×, 2.8×, and 4.5×; attack scales by 1×, 1.6×, 2.5×, and 4×. Nexus damage increases by one at each star after I. Each ability uses its own values listed above.
Generic star scaling does not increase armor, magic resistance, range, or basic attack speed. Learn the recruiting and merging loop or read about tower and marcher positioning.
