Patrick (Technician) Mastery Unlock Priority

If you're playing on a PvE server, the Skill Upgrade Mastery is effectively useless and can be left for last. Prioritize Dodge Count +1 first, then invest in Inventory Weight, followed by Health.
Priority 1: Dodge Count +1
| Required Points | 15600 |
|---|
Since an Inventory Weight Mastery lies along the path, you can pick up Dodge Count +1 while simultaneously increasing your carrying capacity.
Priority 2: Inventory Weight +10
| Required Points | 7200 |
|---|
The upper Inventory Weight branch requires fewer Mastery points overall, making it the more efficient route. It's recommended to unlock all of the nodes along this path.
Priority 3: Health +30
| Required Points | 3600 |
|---|
By taking the lower path and unlocking all of the Health nodes, you can increase your maximum Health by up to +300. If additional survivability isn't necessary, you can instead take the upper path to obtain the Occult Science Weapon Attack Mastery.
Patrick (All-Rounder) Mastery

The following are the enhanced stats when all of Patrick's (All-Rounder) Mastery is unlocked.
- Health +1550(*)
- New Save Weapon Attack +20%
- Inventory Weight +30
- Acquired SPLithium +30%
- Rage Gauge +1
- Skill Cooldown -15
- Skill Upgrade
*Includes Initial Stats
Patrick (All-Rounder) Mastery Unlock Priority

Prioritize Inventory Weight +10 first, as it requires fewer Mastery points to unlock, then obtain Rage Gauge +1. Afterward, work toward the Health branch, which contains several valuable Masteries. Skill Cooldown Reduction and Skill Upgrade provide lower priority benefits and can be left until last.
Priority 1: Inventory Weight +10
| Required Points | 5500 |
|---|
Even when fully upgraded, Inventory Weight only increases by +30. However, the required Mastery points are low, making it worthwhile to unlock all of the Inventory Weight nodes.
Priority 2: Rage Gauge +1
| Required Points | 17300 |
|---|
The next priority is Rage Gauge +1. Increasing your Rage Gauge helps offset lower Attack power, allowing you to maintain strong damage output during Rage states.
Priority 3: Health Increase
| Required Points | 13400 |
|---|
For your third priority, it's recommended to invest in the Health Masteries. There are numerous Health nodes along the path directly below the starting point, but because they require a large number of Mastery points, it's more efficient to start with the lower-left branch and gradually work toward unlocking them all.
