The Mystery of Arpeggio FaultTech Tree[]
Activating Nodes[]
Nodes can be activated for free, providing buffs that apply across all chapters.
Upon activation, you must choose 1 from 3 random nodes, which come in 3 quality tiers.
With each new chapter unlocked, you can activate an additional row (3 nodes), up to a maximum of 5 rows.
Refreshing Nodes[]
You can spend 
Crimson Silk to refresh the nodes, which cannot be undone.
When refreshing, you must choose 1 of 3 nodes to overwrite the current one.
Note: The leftmost node will always be the pre-refresh node, while the other 2 are random.
Aim for an orange-quality node!
