Thinking of Forbidden Chakra in terms of Lore when it was never envisioned as having anything to do with Lore is folly. It's just a damage loss mitigation tool that was originally conceptualized to be used during downtime that was converted into a resource while doing the absolute bare minimum towards that. If it's going to be a fully envisioned gauge, it probably shouldn't be 14 to stick with lore, that's an extremely awkward number to work around. It should be 10/100 like most other gauges because that's a good round number for the human mind to wrap itself around in terms of usability.
