5 of the Protoss have a Mastery option for this. I’m wondering how people treat this since I’m guessing we’ll be all over the place! On one hand, I’ve heard that it can be quite a boon if you keep up on your Chrono Boost macro. Especially if you’ve maxed out on Mastery points for it! (+22.5% vs. up to 52.5% boost in build speed. For reference, that reduces Raynor’s BCs build time from 45 to 34.875 and 21.375 respectively!). OTOH, I tend to forget about Chrono Boosts for some games, and at times, much prefer its competing mastery for certain COs.
Interestingly enough, 3 of them Protoss COs… Artanis, Vorazun, and Karax have this same choice to make:
Chrono Boost Efficiency (1% to 30% boost in efficiency) vs. Initial and Maximum Spear of Adun Energy (3 to 90pts)
For Alarak, it’s between Chrono Boost Efficiency vs…
Structure Overcharge Shield and Attack Speed (+2% to +60%)
For Fenix, it’s betwene Chrono Boost Efficiency vs…
Extra Starting Supply (+2 to +60)
.
For Karax, hands down all into SoA. His Orbital Strikes and Solar Lances are always useful (and what defines him)
For Artanis, I have full into SoA, although I could probably stand to divert some pts into Chrono Boost. I’ll need to take note if I’m spamming his Orbital Strikes and Guardian Shell to the point of running out of energy (probably not?
For Vorazun, Deploy Dark Pylon, Black Hole, and Shadow Guard I do use often, so I’m tempted to keep it full into SoA as well
Alarak, I really dig using his Structure Overcharge Top Bar ability, so that gets the full split
Fenix, I currently have it even 15/15 split, but I should consider going more towards Chrono Boost since I’ve noticed I tend to build more Pylons early on anyways.
