Frequently Asked Questions
How do portals spawn in Anime Defenders?
Portals spawn exclusively in Infinite Mode, starting at wave 30. After that, there's a chance every 15 waves (46, 61, 76, 91, etc). Higher difficulty levels have increased portal drop rates, and being the host doubles your drop rate.
What is the best portal for secret units?
Demon Portal has the highest secret unit chance at 20%, making it best for F2P players. However, Ancient Dragon Portal drops the best quality secret units despite its lower 6% rate.
Do you get better drops as host in Anime Defenders?
Yes! The host player gets double portal drop rates and priority for higher rarity drops. Always try to solo grind Mythic+ difficulty as host for maximum secret unit chances.
What are spirits from portals?
Spirits are attachable buffs that drop alongside portals. They provide stat boosts like +30% damage, -15% cooldown, +20% range, or +10% crit chance. You can equip spirits to any unit.
Can I reset portal progress?
Portal progress is tied to Infinite Mode runs. You can't reset progress mid-run, but starting a new Infinite run resets everything. This is why many players prefer solo grinding.
What's the best strategy for portal farming?
Solo grind Mythic+ Infinity as host. Focus on Demon portals first (easiest secrets), then progress to Ancient Dragon once you have a strong team. Use Gojo for CC and bring AoE units for faster wave clear.
