Leech Swarm Saves and Poison

[Monkplayer]

I'm still having some trouble understanding how the saves and frequency works?

Blood Drain (Ex)
Any living creature that begins its turn with a leech swarm in its space is drained of its blood and takes 1d3 points of Str and Con damage.

I UNDERSTAND THE ABOVE SENTENCE, but how is it cured? A Heal spell or heal skill with 8 hours rest right?

Poison (Ex)
Swarm—injury; save Fort DC 15; frequency 1/round for 2 rounds; effect 1d4 Dexterity drain; cure 1 save.

OK SO THIS MEANS O THE FIRST ROUND THE CHARACTER DOESNT MAKE THEIR SAVE...1D4 DEX DAMAGE AND THEN SECOND ROUND MISSS THE SAVE AGAIN ANOTHER 1D4 DEX DAMAGE? IF MAKE THEIR FIRST SAVE THEN NO MORE SAVE IS NEEDED.

LASTLY, A HEALING POTION OR CHANNEL ENERGY DOESN'T WORK FOR ABILITY DAMGE JUST HIT POINT DAMAGE CORRECT?

In the first case, you can heal the STR and CON damage with multiple castings of Lesser Restoration or one casting of Restoration.

In the second case, you're right on how the frequency works (but remember that 'drain' is different from 'damage'). You'd have to heal that with a casting of Restoration.

No heal check is needed to restore ability damage. All characters restore 1 of each ability damage for each day assuming they rested. Heal check is required only if someone is going to spend 8 hours of their day or all of their day to treat someone (other than themself) for more than the time the victim just slept for. the extra 8 hours doubles daily healing, and spending the entire day quadruples the healing (4 per day).

First fort save is to see if they're poisoned. If they are poisoned they take the damage/drain for that round. For subsequent rounds if the save is made, the damage/drain is not applied, and the poison effect is entirely removed. Some poisons may require 2 consecutive saves in a row before it's cured though (it's specified on the poison when that's the case).

Under default circumstances cure light/serious/moderate wounds spell will not restore ability damage, nor will channel energy, but I wouldn't be surprised if there was a special ability that allowed it to be done.The heal spell (lvl 6 spell) would heal all ability damage, but not any drain. Lesser restoration restores 1d4 ability damage of only 1 ability, but not any drain. [regular] Restoration restores all ability damage and drain of 1 ability.
