首先假设地图不是很大也不是很复杂，15*15~20*20的平地，高度10格左右就差不多了..稍微大点大概也不是不行，不过懒得算了XD。
那么要战的第一步是堆先攻，Tiamat不投先攻，最高的一个头先攻是45，于是采用phb3的skill power（dragon 379还是378的东西，10级perception每日辅助），直接拿被动perception替换掉先攻。Perception我懒得慢慢鼓了随便弄个这东西玩：
Robe of Eyes Level 2+
This fine silk cloth appears to be covered in swirls of color or
peacock feather patterns, but in fact depicts dozens of unblinking
eyes.
Lvl 2 +1 520 gp Lvl 17 +4 65,000 gp
Lvl 7 +2 2,600 gp Lvl 22 +5 325,000 gp
Lvl 12 +3 13,000 gp Lvl 27 +6 1,625,000 gp
Armor: Cloth
Enhancement: AC
Property: You cannot be blinded and gain an item bonus
to Perception checks equal to the armor’s enhancement
bonus.
30级的被动Perception至少有10+15等级+5技能受训+3技能专精+6道具+8感知（不算Demigod等加值，只要初始有18感知就+8了，对牧师来说不算很难）
总共47的先攻，够用了。
/me 比较朴实，不喜欢搞秒杀流，于是接下来就是怎么不被打死的问题。Tiamat那么多威能，最麻烦的大概就是一个遭遇stun以及随意+遭遇的dominate，另外还有个目盲被上面的袍子无视了，剩下就是无数的超高伤害..好在Tiamat的龙威stun不是SV ends，只有一回合，所以可以无视。dominate的话，首先是半梦灵回合初投dominate的SV，然后用phb2的epic专长对charm SV+2，然后装备AV上的这个东西第一回合用掉：
Cognizance Ring Level 16
Inlaid with tourmaline gems, this electrum trinket strengthens
your mind and spirit.
Item Slot: Ring 45,000 gp
Property: Gain a +1 item bonus to saving throws against
conditions with the charm, fear, illusion, or psychic
keyword.
Power (Daily): Minor Action. Gain a +5 power bonus
to saving throws against conditions with the charm,
fear, illusion, or psychic keyword until the end of the
encounter.
If you’ve reached at least one milestone today, you also
gain a +2 power bonus to Will defense against powers
with those keywords.
然后再随便找一个对charm SV +2 item bonus的东西，于是对Tiamat的Dominate回合初投豁免，豁免+5物品每日+2专长+2物品=+9必过，基本相当于免疫。
第一轮用完上面那个以后，用标准动作放这个（dragon 372上的）
Sealing Death’s Door Cleric Utility 22
With a distant boom audible to all, death’s door slams
shut around an area you protect with your divine power.
Daily ✦ Divine, Zone
Standard Action Area burst 2 within 10
Effect: This burst creates a zone that death cannot enter.
When you or one of your allies within the zone
is reduced to 0 hit points or fewer, you do not fall
unconscious, begin dying, or die, and may continue to
act normally (unconscious creatures within the zone
when it is created remain unconscious as normal). No
creature is required to make death saves while in the
zone. When a creature exits the zone, it succumbs to
whatever state its current hit points would put it in at
the end of its next turn.
Sustain Minor: The zone persists until the end of your
next turn.
最后一个minor，用来放Ring of Focus的每日（AV2的24级戒指，效果是可以用自由动作维持）。
这三个用完以后tiamat就只有推3格推出Sealing Death’s Door范围算是有威胁了，这解决起来很简单，比如AV的Ring of Personal Gravity减一格被推距离，Defiant Boots减两格，于是就减到0了。
这么些工作都做完以后，Tiamat就最多只能使我们缓慢、降AB、降AC之类，相当于免疫他的攻击了。接下来随便怎么虐都行，比如说用Demigod的无限遭遇配合Turn Undead的miss half两下就死了。
事实证明tiamat好像也没那么难车..
