Regaining your balance after what would have been a complete miss, you manage a glancing blow.
You attack the giant squid with a machete for 1 damage. You gain 1 XP. It drops to 136 HP.
[-70.643,+26.333]. You know, I could probably kill this one too with my 38 herbs using AP-XP, but... uh... well, then I wouldn't know what to do next. I guess I'd just pump up my kill count while hoping to find upgraded animals and waiting until Halloween. Well, mostly it just doesn't feel right. It would be awesome to kill a Giant Squid straight from 217 to 0 by myself in 1 day, but it just feels weird. And I might wind up doing that anyway in 2 days, if nobody else arrives and chips in.
Edit: Whee! Found it again at [-70.642,+26.325] after expending a fair bit of my daily AP searching. I ran through my 15 darts pretty quickly before going on to XP -> AP, did that twice before finally, with my very *last* AP...
(2012-02-21 01:28) You attack the giant squid with a machete for 3 damage. You gain 3 XP. It drops to 1 HP.
19 minutes left to regain an AP.
Well, anyway, waited 19 minutes and...
(2012-02-21 01:54) You attack the giant squid and miss.
Had 13 minutes to regain AP waited and:
(2012-02-21 02:12) You attack the giant squid with a dagger for 2 damage. You gain 2 XP. It dies. You gain 153 XP.
FINALLY got it.

Out of AP now, so I guess I'll have to stumble north to Durham tomorrow. So, Giant Squid and Python done... I guess now all that's left to do for the next 8 months is wander the island killing animals in hopes of stumbling upon an upgraded one, unless Simon ever brings back the Sacred Space (in which case I'll kill Trader Tamdal before going back to that). It's a long haul from here on. I suppose I can still keep track of squid and python sightings in hopes of getting an upgraded one of those.
