Shifter vs Valgoth

OK, we each start on a 5x5 pillar, 75ft away from a 50x50 pillar. We're on opposite sides.

The pillars are 50' in the air, with ocean at the bottom.

Daily preparations allowed. (Feel free to start the game shifted)

Roll initiative!

I'll start out shifter to a mature adult blue dragon, and with +1 bonus from magic fangs, greater on all my claws.

Initiative:
[roll0]

[roll0]

Let's rock!

And roll! And role!

Your move.

OK, let's see what we can do here ...

I won't go all-out kill this time, so here're some prep spells ...

Targeted Dispel Magic, Greater

Have some rolls ...
[roll0]
[roll1]
[roll2]
[roll3]
[roll4]
[roll5]
[roll6]

Quickened (Rod) Summon Undead V to summon a Shadow that appears 145ft infront me. (Shadow HP - [roll7])

Discharge 3 charges on the belt of battle, to cast Forcecage on myself, as a windowless cell.

Shadow charges you.
[roll8] Touch Attack
[roll9] Strength damage

Your turn.

What was the Dispel Magic aimed at?

And the shadow missed. Touch AC of 25.

I'll become a Wyrmling Force Dragon and attack the Shadow with my breath weapon.

Damage roll:
[roll0]

Worst rolls EVER.

Then I fly back 250 ft.

Also, Save DC is 25.

OK, I made a mistake before, the dispel rolls should've only been +20. Also, they're targeted at you, to dispel buffs/effects/supress items.

Wow, that's depressing, I need a 20 to hit you.

OK, dismiss the forcecage.

So you're 450ft away from me?
