For the Big T, I think you have to go Epic. Skeletons would just be a disappointment and Zombies are limited to 10HD (MM1, 265) for Animate Dead. Maybe this for the spell?
[spoiler]23 DC (Seed: Animate Dead (Epic, 93)) (207K, 5 days, 8.28K XP)
+84 DC (for 48HD that the Big T has, 24 past 20HD times 3 so you control it) (963K, 20 days, 38.52K XP)
-12 DC (Because it'll be a zombie) (855K, 18 days, 34.2K XP)
-5 DC (Because you are a Necromancer, right?) (810K, 17(16.2) days, 32.4K XP)
Each minute lowers cost by 18k, .36 days, and 720 XP. Animate Dead normally takes 1 minute, you can make it last up to 10 minutes before getting into days. Then 100 days with the same reductions.
If a ritual, each spell level grants the following reductions:
Level | Gold | Day | XP |
1 | 9k | .18 days | 360XP |
2 | 27k | .54 days | 1080XP |
3 | 45k | .9 days | 1800XP |
4 | 63K | 1.26 days | 2520XP |
5 | 81k | 1.62 days | 3240XP |
6 | 99k | 1.98 days | 3960XP |
7 | 117k | 2.34 days | 4680XP |
8 | 135k | 2.7 days | 5400XP |
9 | 153k | 3.06 days | 6120XP |
Epic | 171k | 3.42 days | 6840XP |
4 Epic Ritual Participants = DC 14 Spellcraft, 126K Gold spent, 3 days research time, 5040XP spent. It would raise a Big T Zombie if you had 4 Epic Spellcasters sacrifice one of their Epic Spells and stand around for a minute with you.
