Power Rings - How do?

[Omni]

I didn't intend for him to recharge his SP with the Lantern, just that if he loses ring charge due to loss of SP, he can recharge the ring and get his basic moves back. Thinking about changing it to a function of his total SP instead, like it loses charge after 1/2 his SP are used so it scales a bit better.

I would recommend you roleplay the ring as being able to be slowly recharged over time, and can be used even when 'empty' to some degree with willpower, so that it basically functions the same as fatigue, rather than it recharging in big bursts. The power of omnilium can be used to explain that. SP is purely for super moves and transformations, so you never need it to use basic moves.

Am I buying things twice? Do I need to purchase a different move to use a wide blast of my ring if I already have Wide Proficiency and Energy Blast for my ring? Does an AK47 have to be bought for different settings like, semi, automatic and burst? Can I have a move that has the option of being charged or not? Can that charge have different levels of charge or do I have to buy every separate level of charge?

Basically, this. I added a sentence with a gun example to make it even more explicit:
"The price of a move depends on how many ways it can be used. For example, a simple sword only costs 300 OM. But a sword which can be used both as a melee and a ranged weapon (for example, this sword can shoot beams) costs 600 OM since it is essentially two moves. Similarly, a gun which simply shoots always the same way will cost 300 OM, but one with several dissimilar settings (such as rapid-fire, shotgun, and sniper) will cost 300 OM for each setting."

In the case of the AK47 with semi, automatic and burst, I'd probably give it 600 OM because while semi and full-auto are pretty disparate, burst could be considered essentially just using full-auto sparingly. It's similar enough that I'm not gonna charge you 3x. Same goes for charged moves - depending on the degree, I'm probably not going to charge you additionally for 'mid-charge' as well as full-charge. Since the creativity of writers far outweighs my ability to consider every possible contingency in advance, we have this thread so I can judge everything. For the forseeable future, I'll be checking over every single move, including those which other staff have priced.

I'm assuming here that the "powers" like Flight and Telekinesis don't have to be purchased twice if the power does the exact same thing as I intend it to, even if the visual is different.

No you don't need to purchase it twice, you just purchase the power.

Does it matter that the ring will make a big glowing jack to lift something instead of it just lifting to an invisible force?

Depends. Invisible force requires Telekinesis. You can make a big glowing jack with a move, and remote control proficiency if you can control it from afar. It could be almost functionally the same as telekinesis, but visible, if you make it advanced enough (for example a move which can lift, push, pull), but by that point it's going to cost more than just buying the telekinesis power.

Onto the applications of your power ring.

Hard-Light Weapon needs a separate move for each weapon, unless the appearance is purely cosmetic ie changing the colour, hilt. But I would consider a hard-light axe to be different from a hard-light katana, and that to be different from a hard-light bastard sword. Each use would be 300 OM.

Hard-Light Blast has the same deal. You need to choose bullets, or a beam, or whatever. You also need to specify how powerful it can become, if the only limit is how much energy he puts into it. With a single form and variable power (like a beam he can put more or less energy into) it's probably gonna be 600 OM.

Hard Light Shield needs Wide Proficiency as it covers his entire person. It would be 300 OM.

Hard-Light Tethers is 600 OM as he can put more energy into the tethers to strengthen them.

Life Support is part of the 'Survival' power (the very last one on the Powers page). Once you have that power, you don't need to purchase a move. But you do require that power.
