Can't use Disruption Shield or Aegis

[readyready15728]

More or less self-explanatory. I have a point invested in both talents and can't use either. Since it was asked of me before, here is my save:

I am using the Linux version of ToME; this time the Steam edition which is apparently more up-to-date than the one from GOG.

Disruption Shield requires you to be at 25% mana or lower before you can activate it. However, it doesn't deactivate if you later go above that threshold. Yes, this is awful and tedious, since it incentivizes casting spells at thin air after every fight so that its active when you need it.

Aegis can only be used if you have an active damage shield, such as from a Shielding Rune,the Arcane Shielding sustain or Disruption Shield. Once you have one of those, then you'll be able to cast Aegis to strengthen the shield.

While I have no problems with these mechanics, they should be documented.

Surround yourself with arcane forces, disrupting any attempts to harm you and instead generating mana.

Generates 1.65, 1.17, 0.80, 0.50, 0.50 mana per damage point taken (Aegis Shielding talent affects the ratio).

If your mana is brought too high by the shield, it will de-activate and the chain reaction will release a deadly arcane storm around you with radius 3 for 10 turns, dealing 10% of the damage absorbed over the sustain's duration each turn, up to a maximum of 200 total damage.

While the arcane storm rages, you also get 85%, 97%, 107%, 115%, 122% arcane resistance.

Only usable when below 25% mana.

The damage to mana ratio increases with your Spellpower.

Release arcane energies into any magical shield currently protecting you, further charging it by 75%, 87%, 97%, 105%, 112% of its max absorb value.

It will affect at most 3, 5, 6, 7, 7 shield effects.

Affected shields are: Damage Shield, Time Shield, Displacement Shield, and Disruption Shield.

The charging will increase with your Spellpower.
