Goal: Obtain UR decorations at level 3.

Priority:

• Decorations with percentage-based bonuses (e.g., +X% critic damage, -X% damage taken).

• Percentage bonuses scale better with HQ level than flat bonuses.

• Diversify decorations to stack similar bonuses. (Example: 2 decorations at level 3 with +1.5% crit damage = 3% total crit damage.)

Ideal level:

• Level 3 offers the best cost-effectiveness.

• Upgrading beyond level 3 is very expensive (requires 18 copies of the same decoration).

Tips:

• Pyramid: Excellent choice, also useful in Season 3. Provides a construction boost that shouldn't be underestimated.

• Shops: Universal decoration pieces can be purchased weekly in the VIP shop and the campaign shop.

TL;DR: Choose decorations with percentage bonuses, upgrade them to level 3, and diversify to maximize bonuses.
