Lost Chronicles -- A Tabletop RPG Homebrew

Individually. This is the advantage of “multiple attacks” that comes from dual-wielding.

Probably. To tell the truth, I suck at estimating distances, so these might be far too long but I tried to guess them as close to “realistic” as I could.

I’m not sure I understand what is being asked here.

This was a problem I came across during the session I used it for too. The system is based on the Warhammer 40k RPGs such as Rogue Trader and Dark Heresy. Matoran characters were given human-like stats and I thought it comparable to make the Toa about the same power level as the Space Marines. I then went through and tried to use the WH40k enemy list as a baseline for creating the Rahi profiles. So, in theory, it should have all worked out rather well. In practice? Ehhh, not so much. But then, in story most Rahi never really seemed to prove a large challenge to Toa anyway (at least not beyond '01).

All I can really say is that, it depends on your story, but maybe working in evil Toa, Makuta, and similar enemies to go up against might work better. Or, much as I hate to say it because I feel responsible, carry on as you have adjusting stats to your needs.

These types of things tend to be subjective and ultimately up to the GM as for whether or not to include them. I imagine friendly fire for AOE effects is commonplace for realism. As for missing shots, you can always look up the “scatter” section or use a system of your own diving if you want to allow for the possibility of missed shots hitting other nearby objects and entities. It would stand to reason that missing a shot at somebody standing in front of a wall of explosives would result in some kind of consequence since a ranged attack doesn’t just cease to exist when it misses it’s intended target.

This thing is probably the most OP mask in the game and I’m never sure I’d be able to balance it properly. But, in any case, the answer to your question is “yes to both”.

Yes, unless the mask power is deactivated part way through.

Until the mask is deactivated. In theory, I suppose this would allow a player to use the mask nonstop which doesn’t seem realistic, but without the ability to hover it seems highly impractical to attempt in the first place.

Yes. The only AP spent through the use of Kanohi is mentioned in respective descriptions. For example: it costs 1 Action Point for an Iden user to abandon or possess a body.
