Tripod Upgrading Questions (Tier 3)

Suppose I’m at the Transfer Skill Tree vendor and I have equipped a weapon with +1 to a tripod I’m tracking. I get a helmet drop with the exact same +1 tripod skill.

First question:
If I equip the helmet AND the weapon, do the tripod skills stack since both are +1 to the same tripod skill to now become +2?

Second question:
If I decide to transfer my +1 helmet tripod drop to the weapon at the skill tree vendor, I assume it has to go to the same skill. So does the +1 on each now become +2 on the weapon (assuming the success happens)? Or, is the only way to get a +2 on a weapon to find a +2 drop and transfer it?

Sorry if this has been covered. I search with different search engines and while they go over transferring tripods, these specific issues weren’t clearly answered. Thanks in advance for all helpful replies.

Tripods of the same skill do not stack, the one with higher level takes priority.

Possible tripod lvls from gear:
Rare is lv1
Epic is lv2
Legendary is lv3

You can transfer a skill from a weapon to a helmet anytime but it doesn’t stack if it’s the same skill effect. You have to find one that’s high level.
